Say you have a GPU in need of upgrade. >would you buy a second

I'd just buy a new mid-range one. It supports newer technologies and is more power efficient.
Buying another old card would probably be cheaper, but the PSU needs to be powerful enough to accommodate it.
Also, from what I understand the multi-GPU performance really varies depending on your use case

Never SLI or CF before you already have the fastest GPU on the market.

Specs look good with SLI/CF but it has all kinds of nuisances.

Don't do this. It sucks. Doesn't matter what brand.

I went the cfx way, needless to say shit was NOT cash. Some games did pretty well, but most of them were so problematic (stuttering, crashes, gpu utilization under 50%) i just ended up using one gpu. Also consider the thermals, my old case what a shitshow of fans thoroughly set up and it still sounded like a vacuum cleaner.
Also you need a REALLY good cpu to make good use of cfx/sli.

If you can, sell the old one and get a new one.

CPU? Huh, that's new. Why?

Overspent on sli 1080 tis, I'm 50/50 on it, seeing as how the games I mainly play support it (wildlands, overwatch, pubg, bf1), and I'm getting solid performance in other games with my pg279q.

The simplicity of using a new titan xp for a gain of 15% in non SLI games is very appealing, but the the ability to max a lot of games that appeal to me at 120+ fps is really nice

As it is currently, no, because my 750 Ti has no SLI finger.
Theoretically, if I had a GTX 660, then yes, I probably would go for SLI as opposed to a better single card. Mainly because they're still a decent performer, and they're pretty cheap now.

Fucking gaymen niggers
Only use AMD because of muh open source drivers for linux

As a previous owner of a dual-GPU setup I can safely say I will not make the same mistake again.

You enjoy the performance of a GPU 2 tiers below?

Definitely sell the old one and put the money towards a single card solution
