Gaming computer

 I would like to play gameslike TF2, Minecraft,  possibly Battlefield 3, and Garry's Mod. 

Let me know what you think.

That will be more than enough.

Just saw you have mismatched memory, don't do that.

And you have 2 500GB drives, just get 1 1TB drive.

Woops, I did not mean to put in two hard drives. And what do you mean by mismatched memory?

you have gskill and corsair (4x 4gb ) ram in your build.  Why not just pick up 2x8GB of the same brand to get the same amount of ram and have 2 ram slots free for future upgrade?

Sorry, I had no idea I put in two hard drives and 4 ram sticks. Here's the updated verison.
