Ok so i got a gateway gt5662 desktop pc. Came with AMD Phenom 9500 quad core processor, 500gb hd, 3gb ram, and an ATI Radeon 2400xt vid card. I wanna upgrade my video card without havin 2 dump a bunch of money on a new one. I dont need something crazy powerful just something that is better than the one I currently have and that will run the new games like Crysis and COD5 and stuff like that. I know the ATI cards are pretty expensive with the best one they have costing me more than I payed for my damn PS3. lol. Anyways does anyone have any suggestions as to a good video card that is pretty powrfull yet relatively cheap? I'm not looking to spend any more than like $150. Can I use a different brand in my pc besides ATI? Any body have any good experiences with some off label cheap vid cards that still deliver a good amount of power? Any and all reply's appreciated.
