that 7600gt is highly recomended! i used to have one of those on my old pc and on mohaa i would run at a average of 120fps constant and about 90 on cod2 which was nice, only reason i got rid of it was because i got a new system with 2 8800s in but yea them things are very deciving .. there only wee things but damn they work... they also can be overclocked a fair bit so.... oh yea running apair... you will need a sli ready motherboard which i very much doubt you have .. also you need to find out weather you have a agp slot or a pci express slot.. quickest way to do this is open up you pc and where the graphics card would go... if its brown its agp and if its any other colour (more than likely purple) it is pci express Paul
