Asus quadcore 2.25mhz(could be wrong on mhz, cant remember right now, thinking I am on the low side mhz wise) not over clocking but will if it will help. 4 gb of ram. xp sp3 os. I have a nvidia geforce 9600 gt right now. I can play gta iv on medium settings turned all the way up and get about 30 fps. Computer is connected to a 27 lcd tv only playing on 720p 1280x760 I believe. I now am into arma 2 dayz mod but get very low fps, unplayable. I turned settings all the way down even little to no difference. I have $200 I am willing to spend. Ill buy a card off ebay or anywhere. What gpu do you recommend? What should I look for in a gpu? Thanks in advanced.
