What's your budget? The stuff you have right now is awful. If you give me a budget I can give you a far better build.

6 cores is unnecessary for gaming, you only get that, if you are just wanting to burn extra money you have (which is a bad idea. Instead go with a 4 core, 4 cores is just enough to play most games, I would go with the AMD phenom II X4, it's very cheap, and you can get a lot of performance out of it. Also to play games like runescape, really you only need 4GB of ram, if your recording 8-16GB Far as the GPU, I would go with the Raedon HD 5770 it has 1GB of DDR5 ram which should do you just fine, all of that would cost around 234.08 its a very basic rig, switching from console to PC, or beginning (your first) PC.
My setup:
AMD phenom II X4, 8GB ram, 1TB HDD, Raedon HD 5770 1GB, 600 Watt PSU. Runs battlefield 3 on Ultra really smooth.

If we were talking Intel than this would be correct, but its not, the CPU is as powerful as something like a i3. The fx 6300 is the way to go on a budget. If he's going to be gaming 8 gigs of ram is close to essential 4 is minimum.

Regarding your build op, from what I can tell the GPU will reallylet your build down. What's your budget I'll try and make you a better build.
