Try slowing down your ram a little and lowering your gpu voltage and increasing gpu speed. Something like 1300/1700 1.25v, +10v, 1.61v(ram).

I guess this is the place to ask. I am interested in selling my 670 and grabbing a 7970, a decent one(Probably even a second hand one that can clock good). Do you guys think it is worth it honestly? Is there a way I can see some benchmarks of a 7970 at 1200/1250/1300 to see how it compares to my 670 in my Sig (Single card of course.)? Thanks.

I'm now convinced that AMD drivers are horrible. I realize with every driver update I have had one to three problems usually something different each time. My problem now is black ops is terribly glitchy with artifacts, I have tried it with 1, 2 and 3 cards still glichy no matter what I do and I can no longer get 3dMark11 to use all three cards at 100% load. But BF3 and Heaven runs awesomely. The older drivers had no problems before with those games/benchmarks. Its quite painful how many problems I have had. I went through 3 generations of nvida cards without reinstalling windows and doing many many driver updates, I did have issues from time to time usually fixable myself. But these AMD drivers they really need to work on this. I personally love the speed of these cards. Right now Battlefield is so nice with my three cards. But I'm beginning to realize I spend more time troubleshooting now a days then actually gaming.

HD 7970 is faster then a GTX 670. HD 7950 is on par with a GTX 670.

So no, I can't suggest going up there. Just keep your 670.

HD 7970 is indeed faster. But for single monitor gaming, the effort placed into going through the hoops of selling off, then obtaining a new GPU isn't worth the slight increase in performance.

Is hd 7970 a better GPU then a GTX 670? - Yes.
Is it worth "upgrading to" a 7970? - no.

If you have the cash and time to do so, why not?

But personally, don't bother, but this is just my opinion.

Sigh I was not looking for that... "Better" is a very big statement...
I was looking for benchmarks showing how fast it indeed is at ~1200/1250/1300.
But none the less thanks for the input and opinion.

Well, the HD 7970 is indeed faster. It's not worlds apart, but realistically, any thing the 7970 can do, the 670 will be right behind it all the way.. (Maybe 10% performance gap or so tops)

Factor in Tahiti's superior Tessellation performance + larger frame buffer

OR factor in GTX 670's massive OC head room + better performance in some games (Bf3 is the 600 series forte hands down) - The 670 will beat even the 7970 GE in BF3)

Edit: Honestly, as a reference, my 7950 @ 1150MHZ is matching a GTX 670 @ 1200-1250 or so...

And if it matters, the 670 and 680 have a firm grasp in 3D mark "P" scores.

I see. Also my card does ~1200-1223 out of the box. Well ill see how some 7970 owners feel and the scores they get tomorrow and base my decision off of that because I'm going to need to see overclocked numbers to get rid of my "golden" 670.

Personally I don't see 1223MHZ golden. It's a damn good OC for a 670, but not golden (uness you use a low voltage)

I'm confident my 7950 @ 1150/1525 could match your 670 on a game to game basis.

The performance gap between the 7950 and 7970 is quite small.

Aside from clock's, the only differerence is:

256 less shaders.
and some removed texturing units.

Same memory, same bus, same tesselators, and same amount of rops (Difference in ROP count takes a bigger performance hit then texture units)

Although clock for clock performance is utterly stupid for comparing video cards, allow me to.

IF you take a 7950 and a 7970 and have em both @ 925/1375 (7970 reference clocks)

They are within 5% of each other. (Some times the extra shaders of the 7970 don't make a difference)
