I recently upgraded my old pc. Ill be passing it down to my younger brother to replace his overheating xbox 360. It will run the newer games at low quality settings. (eg grid, fear 2), My question is is there anything i can replace in this old dog to get a bit more of a kick out of her? I think the gpu is bottlenecked by the cpu after a hefty overclock with only1 fps increase. I would prefer to replace as little as possible, but will spend a little more if the results would be worth it. Any help or advice would be great ! Rough specs. Intel Pentium 4 northwood. 2.66 ghz socket 478 1 gb of ram Nvidia 512 mb 7600 gs AGP Mainboard Model 0804h (0x134 - 0x22080) 80 gig hd Dvd rw Ive also included a cpuid file. For those more technicaly minded than myself Thanks in advance.
