Gotcha, thanks. I'll probably talk with Hash about building a new one from scratch once I've got the cash and he's got the time.
Yeah, that's probably not a bad idea...it's getting to be that time for your system.
I'd recommend first off setting up a budget for your build and figuring out what all you can reuse from your current system like DVD burners, etc.
You'll want to get a quad-core of 3 GHz or faster, 4GB+ of DDR3 RAM, Windows 7 x64, and the best video card that you can afford...it's one of the most important components...especially with the rest of your system being able to handle the power.
