I'm new to overclocking, I am building a new QX6700 system and my current system is a AMD 4600/A8N32-SLI-Deluxe (939) 2-gig kingston ram/ 2x 8800 SLI/ 2x raptor drives Raid0. I would like to keep this rig intact minus the video cards for my new system. Is this a good overclockable CPU (4600+ 939). What are some good #'s to keep the CPU stable at 2.8 ghz? Thanks guys?
