That's a pretty good processor already. You need windows 7 too, if you're on vista if you want more ram. IMO, buying a good processor cooler, overclocking your current processor to 3ghz or so, then getting a gtx460 would be your easiest and cheapest way to upgrade your system.
I don't know what bios you have, but some Alienware PCs have the option available right in their advanced settings of bios. You hit delete during the boot process(just keep hitting it after you turn it on, before windows starts loading.) Then, you go to advanced, navigate to the overclock option and choose enable. Then let it boot up and see what that does for starters. I never use prebuilt PCs so my knowledge/experience is very limited beyond that. I've seen that option before on Alienware PCs though.
