Actually I've got nothing better to do here's a very detailed guide of what you should go look for secondhand
Also piece of advice if you're gonna go with the idea of getting a ffor parts model and repair it, if it says it artefacts forget it, if it prevents the computer from booting it's a short circuit which is easier to repair in many cases though it can still come from within the GPU die and then you're fucked, if it's not preventing anything but not being detected it's likely a voltage rail isn't initializing properly which might be a very easy repair depending on how willing you are to frankenstein your card with bodge wires, ideal is black screen but detected, best case is just one video out is broken worst case it's the video output part of the GPU and then you can just use the render on one GPU but output on another function in Win10 no equivalent on prior windows so not an option there, and you still need another GPU to output the video then
Keep in mind support for Kepler and down is nonexistent now and before you repeat the meme upgrading drivers does not cause performance downgrades.
Would avoid the following GTX470 / 480 / 550 / 550ti / 590, GTS450, half of those grenade on their own at an alarming rate (590 being the worst), the other is too gimped to be worth it (450 / 550
Would go for:
GTX460 but only the 1GB models, the 768mb ones are gimped on clocks, those tend to heat up a lot so avoid blower style cooler
GTX560 / 560ti, more or less the same deal as the 460 except no gimped models to avoid
GTX580 / 570, those are 300w it's worth a consideration however as it's not very far behind the the 6XX gen though at the cost off eating an insane ammount of power, there's a few model with 3GB and those are maybe worth the extra seeing as the only limiting factor for those is VRAM capacity, don't be a retard and use a blower model you will regret it, 570 is almost the same.
Would avoid GTX670 / 680 / 650 / 690 / 730 / 740 , same deal half of those have really high failure rate the other is simply too small to be worth considering, the 650 is there because it being rarer than the ti makes it often harder to find at good prices and it's way worse overall
It's not great but it'll be in the 560 ballpark without eating 560 power, also can have 2GB which is worth it
It's straight up just a faster 650ti for similar prices
The original 0.5GB meme (2GB on 192bit interface so the last 512MB are slower to access like the 970),
It's gonna be hard to find since there's a ton of similarly named models but, it can go surprisingly cheap (under 150) and it's better binned and built so less self destruction than the 680 / 670, it's a blower but a relatively well designed one so it won't be completely horrible with decent paste and after being cleaned
Goes for very cheap because unpopular, similar to a 650ti
4GB models are sorta worth it but not really, usually they perform better due to higher base clocks, make very sure it's not a 192bit model
It's literally just an OEM 760, it performs the same but can go cheaper sometimes
4GB models are maybe worth it now but they weren't back when it released, would avoid blower models besides the FE
There's a 4GB model which is OEM only and the same performance wise as the 3GB model, though nowadays the 4GB might be faster, don't go blower, even the FE is starting to struggle here
>780ti / TITAN black
Basically latter model faster clocked 780 sometimes with more VRAM, it's still not good or ideal but it's entry level 1080p/60@high material
I know I said the blower was a bad idea but if it's cheap enough the TITAN black is worth it, especially if you're willing to go watercooling as many people will sell them with a waterblock
Would not go for GTX 980 / 980ti, they're great GPU with an hilarious tendency to just die in ways that you can't repair (defects in side the GPU die), many people have ran those on insane OCs which doesn't help the situation
Would go for
Yeah it's Maxwell even if ti says 7XX, meaning it still has support too, a bit faster than the 750 but uses less power
A bit worse than the 760, nothing special
About the same as a 770, same deal the 4GB models are maybe worth going for
Because of the 3.5GB meme they go cheap and because modenr drivers basically makes it so you never hit the last 0.5GB they run rather well, even now it's likely the best value card you can go for as they're faster than 780ti but can go for just around 100 bucks
It's where prices get fucking stupid
If it's under 200 and is the 6GB models, every other model has people trying to push them at 6GB model prices and that's simply not worth it.
If it's under 250
if it's under 300
if it's under 500
Past that point the prices are too high to be worth it and you're better off hunting for a 3060 at a decent price.
Well there it's much simpler, anything prior to Polaris is not worth going for because bad support and having to juggle drivers and Polaris is very fucking pricey for what you get, if you see a 470/570 for under 150 then it's sorta worth it and that's all, better off trying to get a 6700XT / 6800 for a decent price.
