eventually im gonna replace my 750w PSU with a 1200w and put a 2nd 7950 in XFire.

I feel a 1200W is overkill for a 7950 CF, you could get away with a good 750W PSU or a 850W.

Yep, I ran 7970s in Tri-Fire overclocked to 1250mhz each with a 2500k @ 4.7ghz 1.515v on a TX850

You can run 3 7970s on a GOOD 850W PSU, but I wouldn't run any more than that. I ran that setup for a long time without a single issue. And prior to that I was running 3 6970s on the same PSU/Rig. Now I'm running 4 680s on my 1200W just fine.

My Current PSU doesnt have enough "PCIe" Power Cables, and I refuse to jack juice off the HDD Cables...

So Im gonna have to upgrade to get enough power cables.

.

My post was alluding to whether or not my 7970 score of 48.8FPS was good for stock 7970 at 2560x1440

Not whether or not it was a good thing that my new 7970 scored higher...

My trifire 7970s with 5ghz 2600k pulled over 1100w. My current rig, quad 7970 w/ 5ghz 3820 pulls around 1600w.
