+1; this build will suit your needs perfectly!

OP, do you need an OS/Monitor/Keyboard/Mouse in this budget?
 
GTX 970 is nearly 2x faster than GTX 760 and has 4GB VRAM . for gaming i5 is enough . H81 boards usually have PCI-E 2.0 slots like their mobo . Also the cooler of the GTX 760 is not so good .

As you wish . The pre-build rig will run games but not on Ultra .
 
I wouldn't get it because the GPU is weak. This build would be much better as it has more bang for your buck:

The 4690K isn't needed as overclocking yields insignificant performance increases and outputs unnecessary heat
The motherboard is a quality unit that supports SLI
You don't need expensive RAM
The GPU has a higher factory overclock and has better cooling
The PSU is a very good unit from XFX that's modular and can support two 970s in SLI.
 


Wait, when was the GTX 970 released? :O
