Three things:
Socket 754 uses single channel for memory so it may well be cheaper to get 1*1024MB stick
500Watts might be overkill for that system, I also don't know whether Aspire make good power supplies, you'd probably be okay with a good quality 400Watt supply, unless you are looking to have it last you a few upgrades.
If you have an unlimited budget the 6800GT would give you better performance (you probably already know that though)
