I have come up with the following build, but I really need to know if all of these parts are compatible (I wouldn't mind some constructive criticism concerning the quality of the parts, either). Please tell me if there is a part that isn't compatible with the rest.

Processor: Intel i3-3220

Motherboard: Gigabyte GA-H61M-DS2

Graphics Card(still unsure about which one I will be using, so please just say if any of them require higher end parts than the ones on this list) : Sapphire Radeon HD 7770/Sapphire Radeon HD 7850/MSI GeForce GTX 660

RAM: 4gb Corsair XMS3 DDR3

Hard Drive: 500GB Western Digital Caviar Blue

Power Supply: Corsair CX500 500W

Case: Antec 300

Thanks in advance:)

Supposing I wanted to game on a 1600x900 monitor, with best performance/price.
 


What games? It makes all the difference. BF3 I'd say 7850 or higher. Wow or Sim City ...7750.

Guild Wars 2, Far Cry 3, games like that.
