Building myself a computer for the first time, and I have most of the parts specced except for the GPU. I don't play a lot of video games, so my first priority is getting something that can display output at all; but I would like something a bit capable, as I do play some 3d games from time to time. Prefer an nvidia gpu, as I would like to play with some nv-specific features (nv_path_render, maybe cuda), but not a hard requirement.

I've spotted the following gpus on craigslist:

• gtx 1070 - C$260 (~$200 usd)

• gtx 1660 super - C$320 (~$250 usd)

• gtx 1070 ti - C$300 (~$230 usd)

• gtx 1050 ti - C$120 (~$90 usd)

Any suggestions? Something else I should look out for? Are these good prices?

TL;DR: How long should a graphics card last? What can I do to make them last longer?

This is perhaps an odd question to ask, but I've been a console gamer for most of my life and have only been all-in on PC gaming for maybe 1-2 years and I think I may be missing something.

So there has been about three times when I have spent money on a half-decent graphics card, and each time they have failed me. The first one was a genuine hardware failure, probably a memory failure judging from the artifacting. The second one failed for reasons I have been unable to figure out. It didn't appear to be overheating, but I was getting driver errors that suggested it were; reinstalling from scratch did nothing to fix it.

The last, most current one is the one that bugs me the most. I'm getting the same problems; driver crashes just like overheating, except this one has better temperature monitoring and I can see that isn't happening.

I previously thought that the reason why my graphics cards would always crap out on me was because those were cheaper cards from less reputable manufacturers, but this last one is really bugging me because it's relatively high end and from a reputable manufacturer - it's a Gigabyte Radeon RX 5700, complete with the giant AMD reference cooler. I'm getting it RMAed, but since I didn't keep the receipt I am still going to have to pay to fix it even though it should theoretically be under warranty.

I've done a ton of searching to find out how I can possibly solve this myself, but I am frankly astounded by how little information the drivers give out on Windows. I'm seeing that the device is being reported as unavailable but nothing whatsoever as to why.

To make matters worse, it seems like this isn't actually common for other people. Most people seem to be replacing their graphics card because they are obsolete, not because they physically fail.

So basically what I am asking is, how long is a graphics card actually supposed to last for? Do I just have astonishingly bad luck?
