My parts will run a lot more than just Aces High, if that's what you're looking to do.
DaddyAce's linked post looks like a pretty good price to performance ratio, especially if you're only looking to do some casual gaming.
I'm also a newb, I haven't even started ordering parts yet! I've spent quite awhile planning, rethinking, and changing a bunch of things around and I'm only finally just getting settled in to what I want with my budget capped, which turned out to be 1500. You can get maxed out performance in AH for much less, something to keep in mind.
