So, I am purchasing a new mobo (EVGA nForce 680i SLI NVIDIA Socket 775 ATX Motherboard / Audio / PCI Express / SLI / Dual Gigabit LAN / S/PDIF / USB 2.0 & Firewire / Serial ATA / RAID) to go with my new build and I had a few questions about this supported ram. Apparently this mobo will run 4 gigs of dual channel 1200Mhz DDR2 (SLI Ready) ram. Are these sticks even out on the market yet? Also, it says the mobo will run 4 gigs at 32 bit, but it will run 8 gigs at 64 bit. Is 64 bit even on the market yet either? I think this mobo is way ahead of it's time. What do you think? Thanks.
