GPU recommendation for gaming pc

[NovaTronMC]

A year ago i just built my gaming/editing pc, this are the specs:

- Intel Core i7 4820k
- Asus p9x79
- Asus GeForce GTX 660 OC
- Corsair H80i
- Corsair LX128 SSD
- Seagate Barracuda 2tb
- Corsair CX750M

And i just bought a NZXT Hue and some Corsair SP120 led fans.

But the question its... if i want to add a Msi GeForce GTX 980 4gb to it, will the performance improve much more? Will i need to change my 750 watt power supply to a 1000 watt one???

Do you really recommend me that GPU? I want a good gpu that will run every or alteast almost everygame at high 60fps.

Or if this gpu its bad, which one do you recommend me???

I would go with a 970 and overclock it. For the price, the 980 doesn't have nearly as much overclocking headroom and a nicely OCd 970 will almost match a stock 980 for much less. Would be great for 1080p or 1440p @ 60hz.

750w should be enough, but the CX series PSUs are midrange quality. I'd personally like to see you use something better if possible.

Ok, but a MSI Gtx 970?? Any model in special? Like ti or which one??

And i have some money storaged only for my pc, which is a good 750 psu? I really like Corsair and coolermaster but which one would you recommend?
