Building PC System - Gaming (Need Help)

[Gi Ter]

Hi guys

I want to build gaming PC, but my budget is limited 600-700$
I own: Haf 932, Corsair HX850 & Cooler Master Hyper 212 Plus(is this norm cooler for new cpu ?). and HDD Seagate 750GB
So components i need to buy are CPU, Motherboard, Memory & graphic card

i can't decide which one to buy i5 4670k, 4690k or i7 2600-3770-4770
Graphic card is also hard to choose, Radeon 280,290 or GTX 970 ?
Memory and Mother have no idea

The i7's are a little out of your budget unfortunately, and I definitely wouldn't invest in a 1155 socket build anyway. Between the 4670K and the 4690K it's hedged slightly to the 4690 simply because it has less overheating issues and overclocks slightly higher(not better, just higher) than the 4670. But either one will be viable for years, and will play AAA titles fluently.

Just go with the 280 now, and plan to crossfire later if your budget allows for it.

If you have the extra $50 and it's not a beal deal, then yes, it's definitely worth it
