Re: Is my PC Crap?
Well. From Newegg, you can get the system for $1502.90, however I couldn't find an APower PSU, so added a PC Power and Cooling one in to the price for $269.99 and the motherboard model wasn't specified, so I went for the GA-X48-DS5 at $189.99. Those may be more expensive than the ones you're being quoted, or they may be cheaper. If you were to assume that they were the same as the ones in the machine you'd be getting, then you're paying the company $300 to build and test the computer.
Is that something you're happy with? The computer itself is fine - more than capable of running the games that you've mentioned (should cope well with most current games, too).
I don't know if Newegg is the cheapest/best place to get prices from, but it seems to be popular amongst the American users here, so it's what I went for. :P
