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?
