im looking for some great DDR ram for my MSI K8T Neo Fis2R mono with an A64 3000. I was looking at the Corsair XMS Extreme Memory Speed Series, 184 Pin 512MB DDR PC-3500C2 with Platinum Silver Heat Spreader, and the Mushkin 184 Pin 512MB DDR PC-3500 Black Hi Perf Level II memory. Which one should I get, or maybe something else I dont know about? I am building my computer mainly for gaming.
