I am in the process of building a new gaming PC and have limited my cpu/motherboard choices down to a socket 754 A64 3400 with a MSI K8N Neo Platinum motherboard or a socket 939 A64 3500 with an ASUS A8V Deluxe. The only reason I would go with socket 939 is for future upgradability, but I am not sure if it is worth the extra money. I don't plan on having to upgrade again for at least 2-3 years and at that time I am sure PCI Express and DDR2 will be standard. So I may have to buy a new motherboard and cpu anyway. The extra $131 is not that huge of a deal but I would hate to waste that money if I didn't have too. Any suggestions?
