For high budget or low?
I'm getting one that you could call it a budget motherboard because its only 100$ but its actualy of very high quality and is REALLY good for overclcking.
the DFI Infinity nF Ultra II M2
Its only cheap because it has a Nforce 4 chipset and not Nforce 5. and the diffrence is not so great..
Also one of the biggest and few advantages AM2 has over 939 is the DDR2 support, along with the on-die memory controller which reduces the access time tremendously[which is the biggest problem of DDR2, the latencies..], it truly shines.
