Everything on there has upgradability, and is pretty damn good on it's own. You've got some of the fastest ram out there without jumping to DDR3, you've got future SLI compatability, you've got an LGA 775 motherboard that supports quad cores in the event you ever want to upgrade to that (Although the preformance boost at the moment isn't really worth it right now).
And while I know you said you have drives coming out the wazoo, You should really consider something like this to put your OS on:
SUPER TALENT FSD32GB25M 2.5" 32GB SATA Internal Solid state disk (SSD) - Retail

It may not be something you want to do now, as they're so expensive, but there's a definate preformance boost with a solid state drive. I know my next build will be including one, though that's not for another 3 or 4 months(I hope).
