User blog:RoflBomb/Specs for a good PC?

I'm interested in knowing what the specs are for a decent gaming PC. I'm not talking about just for playing Skyrim and the other Elder Scrolls games and Fallout games, but also for Battlefield, and maybe for other multiplayer games. Its getting irritating playing on the PS3 and all the problems its been gathering during the past few months, and I'm not interested in buying an Xbox, since I've gotten the RROD, and then getting it repaired only for it to start burning rings in my $60 games. So if anyone can give me the specs for a good PC, and/or give me advice for building a decent PC, it would be greatly appreciated.
