I'm building my first PC and I decided to keep it at around 500 - 600 dollars. I've done a lot of research and this is the best I have found for the price
Cpu: Intel i5 3570k
Mobo: H61M-E33/W8 LGA 1155 H61 mATX Intel Motherboard
RAM: Using from old prebuilt computer (8 gb)
PSU: Corsair CX430
GPU: GTX 760
Are there any other parts I could use to optimize it for gaming?
