As the title suggests, I'm looking to build to new gaming pc for ~$800. So far, I've picked out the following components and would appreciate it if I could get some feedback to make sure there will be no issues down the road.
I don't think Thermaltake's are highly rated PSU's, and the fact that it's 40 bucks for 700w also seems suspect. Go with a PSU from Antec, Seasonic, Corsair, XFX, it's probably the most vital part of your machine considering it touches everything else and if it fails it can take a lot of stuff with it.
I agree with the above.
Also, I'd go for GTX 660 out of those two. It's considerably faster.
