That's not correct. The free version can do 99% the same as the studio version for most users, you're only missing out on resolutions bigger than UHD, it doesn't have the noise reduction and film grain OFX, etc. For normal editing and grading, it's widely the same.
I don't think it makes sense to invest any money into your system if you haven't actually identified a bottleneck. I would edit/grade a project and run resource monitoring to find out if you every approach a limit regarding CPU, GPU or storage. There's no benefit to increase e.g. GPU performance up to 200% of now when you maybe never reach over 60% currently.

Also also also...  being able to apply multiple treatments to an image is really where professional colour grading begins.  You'll see in every colourist / colour demo that they start with the image and then they'll show several wipes to show how they did something, then something else, then something else again, etc.  That really needs multiple nodes to do as you need the full control of one or more nodes to properly do each correction.

Also also, having multiple nodes allows you to have parallel processing of the image, for example you can take a key of an object, split it and the rest of the image into two separate paths though the node graph, and for each one you can have it pass through multiple nodes, before they get combined again.

Also, I forgot that multiple nodes allows you to do things like layer adjustments and parallel nodes, which allow all the kind of effects that having layers in an image editor gives you.

That's what I thought as well.
It doesn't directly talk about your setup, but there are a bunch of articles on Pugets website talking about what benefits you get from having multiple GPUs, like this one:
https://www.pugetsystems.com/labs/articles/DaVinci-Resolve-14-GPU-Scaling-Core-i9-vs-Xeon-W-vs-Dual-Xeon-SP-1121/
Of course, buying a second GPU also means buying Resolve, so it's more of an investment.
I found with my system that the CPU was the bottleneck until I added an absolute ton of processing, so I had to upgrade to my new laptop.
You can use the Activity Monitor application under Utilities to see the load on your system (go to Window and enable CPU History and GPU History then go do things in Resolve and see what got maxed out).
I would definitely upgrade to Resolve Studio.  IIRC the free version of resolve only lets you have a single node?  If that's the case then having the ability to have more than one node let's you do a few killer things:
Choose what order your effects get applied in by separating them into different nodes You can start to work with selective adjustments where you take a key and adjust only certain ranges of colour (eg, skin tones) or certain areas within the image (eg, track a moving window on someones face) Apply multiple OFX plugins Use Temporal Noise Reduction that compares multiple frames to do NR instead of blurring just one frame at a time

If there's no bottleneck, I personally would save my money haha. I think that for normal editing, your 1080TI probably already outperforms your CPU so adding another would likely give no benefit.

First if you're editing high bitrate footage from an external HDD make sure that's not the bottleneck. A 7200 RPM drive reads at 120 MB/s, even even two uncompressed 14 bit HD raw streams would go over that.
I have a GTX 1080 and use Resolve Studio. Earlier this year I upgraded from an i7 4770 to a Ryzen 3600, and got an enormous performance boost when editing HEVC. So while the decoding is done on the GPU, it's clear that the CPU can bottleneck as well. When I edit 4K H.264 or Raw my 1080 rarely maxes out.
Overall I'd be pretty surprised if you need another/a new GPU for basic editing and color grading. Resolve studio is a better investment imo than a second 1080.

Honestly just save up for new rig mate it would be better option
Or get another ti and have it sli .

If you're never hardwiring yourself to a camera, then you've got nothing to worry about.  Otherwise, use a phantom blocker. ( I never have, as when I used my F4 I was only rarely hardwired and when I was I just simply took care with what I was doing)
 
They should do the same job, but the Triton Audio is smaller. 
 

Triton Audio do a bi-directional phantom power blocker.
Not cheap at £36 per channel but cheaper than buying a new F4.

@IronFilm, slightly off topic, although mentioned in this thread... I recall you saying somewhere that the 32-bit float option was a bit overrated. I was toying with the idea of upgrading from my Zoom F4 to a mixpre-6 for the slightly better analog limiters, but then I was thinking that a mixpre-6 II might be the final destination purchase for a primarily audio doc producer like myself whose needs are already well covered by a 4 xlr in recorder, but can see the value of 32-bit float in situations when you're capturing a really loud concert or a passionate discussion with multiple talking heads.
Point is, if you were 90% satisfied with the F4 but willing to make one final upgrade on your primary audio recorder (though not a rush to upgrade either) --- would you upgrade to a used mixpre-6 or hold out for the mixpre-6 II?
And thanks for all the audio advice you offer us all on these forums!

There are two main perspectives here:

Production Sound Mixer:
32bit is pointless, and non-standard.
Heck, there isn't even a single professional field recorder in existence that does 32bit!! Not one.
Needless it say it is not desperately needed by a PSM.

One man band videographer who does everything himself, including even audio post:
Their attentions are being pulled a million different ways during a shoot, as they're trying to do too much, and thus mistakes might be made. And they don't need to worry about surprises in the post workflow, as they're handling this all themselves. 
 
Have you done the latest firmware update for the F4? For its hybrid digital limiters.
(btw, note that almost everything on set is wireless.... so often by the time you hit the recorder, the limiters there are too late as the damage is already done)
In my opinion (note: this is from the perspective of a PSM):
It is a big step back to go from an F4 to a MixPre6mk1. 
Just some of the negatives:
No dual media recording
No safety track recording. 
Two less channels than a F4 if using TC
Inferior powering options
Ergonomics/design is a step back

An alternative opinion, if you're a OMB videographer:
The MixPre3/6 is a very compact form factor for mounting under a mirrorless camera, and worth the so called "upgrade" just for that alone. 

 

I believe the Zooms loose a lot of power when left inside. Also they need to be pluged occasionally, so not to loose internal clock and the such.
I don't remember exactly, but after some time, both my huge NPF batteries AND the Eneloops inside, I find them dead.

Has been a while since I used the Zoom F4, heh, used it only once in the past year perhaps?? I ought to sell it. 

But I always powered it externally, so the exact amount of internal power left didn't bother me too much. 

However from memory, it always remained more or less the same? Even if it had been months since I'd charged the batteries. (as I'd only be charging my external battery!)

If you're in doubt, and freaking out, just turn it on for a couple of minutes before you leave and check yourself!
 

He's totally free to push the limits of people's personal boundaries within public spaces for the sake of his art. By the same token he better be totally ok with the potential repercussions of his actions. Matter of fact, I'm sure he instinctively picks his subjects/victims based on how much of an immediate threat they might pose to him, which speaks to the predatory nature of his behavior... and that's regardless of whether his end goal is art, creepy kicks, or both. But to me the scarier people are those who can't just acknowledge that all these things are equally legitimate factors worth acknowledging when deciding whether what he is doing is actually worth it, for the sake of art... or whether there might actually be a way for him to do his art, while respecting the boundaries of his subjects (what, too hard of a proposition to wrap his boundary-pushing artist head around?).
Personally I have way more respect for the artist that cares about that part as much as they do their precious art.
 

Don't get me wrong, i am enjoying the platform too. My iMacs have been real workhorses and FCPX is a gem. 
But when you get into a situation similar to the one i described above you are forced to reconsider the real value of these products, especially the hardware part.
Imagine paying 4500$ from your hard earned money for a laptop and then plugging in your earphones to avoid listening to the 2000 pops that will be produced during an editing session. Then imagine claiming your customer rights from a company that like @kaylee said above "doesn't talk about it". 
Also, the customer support in USA is way better than here in Europe. 

+1 for tungsten, unless you book alot of time sensitive gigs that require you to pack up and leave fairly quickly, which is something that can be easily forgotten/overlooked if you're not used to working with fixtures that need time to cool down after they've been used.

Looks like it only allows SSD's up to 1TB in size (or maybe I'm misunderstanding the specs) while the Nexto allows for 4TB SSDs and technically can take drives up to 32TB in size, which seems like a much better long term investment. 

YouTubers have been promoting the new Gnarbox 2.0 which looks kind of cool.
IIRC it has ability to plug in an external USB drive for storage, as well as a USB port for an external card reader, and can do cool things like backup a card to the internal and external drive at the same time.

In case people haven't seen Nexto's latest backup solution. Comes in a few different configurations including one that includes a CF slot: https://www.nextodi.com/products/nps-10/
Anyone own/use one yet?

yup got $600 back!  and a free repair! consumer advocacy works!!!! I reached out to their sales rep about the matter  - I'm not taking full credit, but I reached out and we should all do this about any product if we are not happy with it.

I remember doing a sh*t load of research into LTO drives and there was one thing I found out that made me not do it... just can't remember exactly what it was, sorry...

Don't they have a file size limit? 
Correct. If you're only storing a couple hundred gigs, or even a TB or so, it's not too big of a worry. It's when you start getting in the 10's of TBs or more that it becomes an issue where you're kinda held hostage. It's not as simple to switch Cloud services when you're dealing with such a massive amount of data. 

Cloud services are convenient at first but quickly become expensive and hard to move away from once you have a lot of data in them.
Bottom line is video data is incredibly burdensome no matter how you want to store it.
