Should I jump to this upgrade?

[Azurenys]

Hello!

I have the build in my signature, pasting it here anyway:
* CPU: I5-4440
* MOBO: ASROCK B85 Pro4
* HDD: 1T SG SATA 6G/7200/64M/3Y WARR
* Case: CM N300 BLACK /USB3 /NO PSU
* PSU: FSP Raider 550W
* GPU: GB N660OC-2GD GTX660 2G GDDR5
* RAM: 8G DDR3 1600 GEIL BULK
* CPU Cooler: CM HYPER 212 EVO

Now, I've been meaning to upgrade this thing and the spot, of course, has been caught by the 970 GPUs by nvidia...
For example, http://www.newegg.com/Product/Produc...82E16814125685
Would my system benefit from it or will the cpu somehow bottleneck the card? Also any idea of my mobo/psu are compatible with it?
Is there any other worthwhile upgrade that would be better than a new GPU (excluding SSD)?

Thank you in advance for any help given and happy holidays!

If you play only WoW, you'll get very little benefit from it. If you use other GPU intensive games, it will certainly make a difference.

Yeah, I play all sorts of games but the real question is will it fit my system or would I need to upgrade something else as well?

[chazus]

I don't see any need to change anything else on there. It fits in the case and the PSU is more than strong enough.

Awesome, thank you! :-)
