I am planning to build a new gaming PC since my agp graphics card and my skt478 p4 processor are a bit outdated. It will have nvidia 6800 pci exp but I dont know weather to stick with intel or move to amd. I know nothing about amd apart from they are supposed to be good for gaming, my current processor is a intel p4 3.2ghz 1mb cache skt478. I need a amd recommendation which is about the same standard as my current one and known to be good for gaming. The amd website says the athlon64 fx is supposed to be good (how many ghz is that?). My current geforce 5600xt 256mb agp 8x graphics card, on high graphics and 1024x768 res, gets around 30-40 fps on counter strike source - would a 6800 do the job nicely? And also is a sata hd really worth it?
