help My First Computer Build!

Hi!
I'm a complete noob when it comes to building computers and would like to put together a simple, cheap gaming rig preferably under 600 dollars (a low budget i know, please forgive me!!).

Would these components be compatible and would they give me good performance in, say, blackops, skyrim, minecraft, Kerbal space program, etc. I would not be too interested in crazy high settings but medium at 50-60 fps would be nice.

Here's the list,

AMD fx-4100 quad core
Gigabyte 78LMT-USB3.0 Mobo
Radeon 7770. ( possibly upgradable to radeon 6850 or nvidia equiv.)
8gb of cheapy 1333mhz ram ( not important)

Running windows 7 64bit

I have not listed the rest of the parts as I do not believe they will affect the performance of the pc so much

Thank you very much for your help

Thank you for the quick reply!

It's a coolermaster 900watt, don't worry , plenty of power.
Would the 250 fps be with the 7770 or the 6850?

Why don't you go for an intel i5 instead of that AMD processor? They are not what they used to be, in terms of games. Intel now has the lead in processing power.

Nah, it wouldn't bottleneck. I'd still say stay with the AMD though. Not much point moving over to Intel cause of the hassle.

Though, a build like this:

- i5 3330 (100-120 dollars)
- H77 mobo (60-80 dollars)
- 8gb RAM (40-60 dollars)
- GT 620 graphics card (50~ish dollars)

That would cost slightly above your price range.
