If you've got the money, go with Pentium. If not, the AM2 will do. I have a M2N32-SLI and it's an alright board. The only problem I had is it's hard to overclock with my RAM. If you end up getting an M2N board make sure you do reasearch on which RAm you can use. I use 2GB of Corsair XMS DDR2-800 and it works fine. I got it clocked to DDR2-900, so not too bad.
