So I'm looking to build a media center for the home and I already had a 939 motherboard and DDR memory laying around. Go over to newegg and purchase an X2 3600 for socket 939, $50 Shipped. I didn't even know they made the 3600 for the 939. It looks like is has 256k of L2 cache per core. Will I notice the fact that I'm working with only 256k per core? What type of performance penalty (if any) am I looking at?
