ok, so i was thinking of buying a new EVGA GTX 285. but, seeing as my current PSU is only like, 400 or less watts or something (horrible, I know, I know), I'm pretty sure I'm going to have to get a new PSU as well. I had this one in mind: http://www.newegg.com/Product/Product.aspx?Item=N82E168... would this one work, and if not, can you recommend one that would (preferably like $120 or less)
That PSU will work just fine with a single card setup. However, if you choose to upgrade and want to run 2 cards you will need to upgrade again. Refer to this article for complete info: http://www.tomshardware.com/reviews/geforce-radeon-powe... . I just purchased a GTX 260 C 216 and according to that page I can SLI them because I have 3 X 19A 12V rails on my 650W PSU. It would cut it close, but it would be possible. What are your system specs?
I considered a 285 and got the GTX 260 C 216 because I got a great deal on Newegg. The marginal gains with the 285 for the price wasn't worth it at all. The 2.7Ghz is decent for gaming. My first gaming rig was a 2.0Ghz X2 and a 7900GS. I played at 1024x768 - 1280x1024 and it played pretty well. I would get the GTX 260 C 216 and find a nice CPU upgrade if you want to spend with the money saved.
