Help me decide on gaming pc specs

[coopertroopa]

I'm looking to build a new computer and need some advice on whether i should upgrade some of the parts, if i missed anything i need, and if they are compatible.

I will be using the computer for gaming regularly.
I'am currently deciding between this setup:

CPU: Intel 3rd Generation Core i5-3570K
MoBo:Asus P8Z77-V Motherboard
PSU: Corsair 600W CX Series V2
Case: Antec Three Hundred Two
RAM: Corsair CMZ8GX3M2A1600C9 8GB(2x4g) 1600MHz
HDD: Samsung F3 HD103SJ 1TB
GPU: Asus nVIDIA GeForce GTX 560 Ti
Optical Drive: Sony AD-7280S-0B 24x
I intend to buy a monitor locally.

or whether i should downgrade the CPU to a Core i5 2380P and the motherboard to an ASRock B75M-DGS, and then spend the money i save on a better gpu.

Im not sure if i need any extra cooling system or not or if i have missed anything else important.

Any and all advice would be appreciated

Actually, that pretty nice, and the 560ti is a great card. Its my opinion that after the 560ti, the performance vs cost degrades.

I would NOT get a CX for a build of this quality and performance. A TX or HX is a must. Compare the cx 600 with a 650tx and you'll see why.

Notice the Amps on the 12V
