What kind of ram would I need to get the full performance out of this cpu?

It all depends how stable your motherboard can be at higher memory speeds. I
suggest read some reviews of it first. Secondly look around for some faster ram.
This is the tricky part since most faster ram is really better binned standard stuff
that would require higher volts. This is hit and miss. I got a 4gb kit that worked
at 450mghtz and saw a sale for a 2gb kit that could not do past 405. The voltages are around 2.1v.-2.2 v max.
