ive heard from a lotta people that epox boards are good for OC'ing, but ive also heard that the athlon xp 2100 is not. now i wanna make sure that i can play doom 3 on medium settings when it comes in. thats why im buying a radeon 9600,. the 2100 runs at 1.733 ghz. is this gonna be enough for medium, or should i OC it. i got 2 case fans, and a huge heatsink and fan for the CPU.
