I really don't care about running GTA using high graphics. I just wanna play it with decent FPS (30+), no matter the settings. For me, my NVidia Geforce 6200 AX does its work fine. I just need to change my processor to a dual-core one, and improve my RAM to a DDR2 with at least 1.5 GB (2 GB would be awesome ), and I will be happy as there is no tomorrow ^^
So I need a new motherboard for that, and a cooler, if the processor doesn't include one.
