Hi all. I just got some awesome components from a friend. I've using laptop for years. I always wanted build a awesome desktop. Here's the stuff I have: Board: LANPARTY UT nF4 SLI-D DFI LANPARTY UT nF4 SLI-D 939 NVIDIA nForce4 SLI A... RAM: 4Gb XMS3200V6.2 2X Raptor 74Gb. 2X 7900GT. A 600Watts PSU. All I need is a processor. Please don't tell me to upgrade. I want to get the most out of my current components. So what is the fastest CPU I could get for 939 socket? My board only supports Athlon 64 X2 / Athlon 64 FX / Athlon 64 CPU. Thanks guys.
