No offense, but pairing an i7-860 with 1GB of RAM would be a horrible balance either way. You shouldn't plan on keeping the computer at all, but either build a new one yourself from scratch (slightly more expensive, depending on where you live) which will give you a lot more flexibility and better quality parts, or just buying a new branded PC like Dell (if you don't plan on doing much with it, and are fine with basic hardware). I'd say it would be a good idea to lurk forums and check the suggested builds for $xxx to get a feel for what's out there, and more importantly, understand why decisions were made so that you have the flexibility to make better decisions for your own situation (cost/use of computer).
