This is my build aimed for d3, LoL, and web browsing. I would like decent fps to play smooth.
Also can you guys check if everything I have is all compatible and set to go before I buy it to start on it.

Wheyou get good playable frame rates depends on the resolution of your monitor .

But here is a Radeon 6770 for $84

which saves you money and increases performance

Using a single stick of RAM is false economy . The computer will perform best with a dual channel ram kit
This kit cost a little more but will increase system performance a lot

Consider an AMD motherboard and processor

Fx 4100 processor $110

ASUS M5A78L-M LX PLUS AM3+ $60

Performance will be the same in games , and better in many applications
