If you could have waited a bit the HD 7970 Ghz editions are due this month. the 680s are amazing cards too. so enjoy thumb.gif

Are you comparing a 670 to a HD 7970 ? then you are completely wrong. if you are overclocking a HD 7970 at 1250+ speeds is the fastest card. biggrin.gif

If you want to run CF at those speeds watercooling is your best option.

Have you owned them to say such thing?

@OP:

I've had gtx 580's, 7970s in crossfire, and 680's. Don't waste your time with the 7970's, they OC high, but the software always crashes and the experience sucks.

If reviewers don't install the latest game patches and show poor CF scaling as performance benchmarks it says they aren't doing a good job. check out this review which shows excellent perf on HD 7970 CF with the lowest amount of time spent in frames which take beyond 50ms to process.

Radeon HD 7970 GHz Edition chips are due to released soon. specs seem to be 1075 core 1500 memory. you will hear more at computex

http://www.techpowerup.com/165559/AMD-Readies-Radeon-HD-7970-GHz-Edition.html

latest batches "easily" hit 1250 MHz core. I think AMD will allow such speeds in CCC biggrin.gif

That is a statement without proof. If you can get it to perform stable with good temps (< 80c) and low noise what more is required. The sapphire HD 7970 OC review proves that

"The stock Sapphire HD 7970 OC Edition had an Idle operating temperature of 27c which increased to 56 degrees Celsius under full load with fans only increasing to 46%. On the Overclocked Sapphire HD 7970 we had fans set to 70% to keep heat off the card under the extreme overclock, and even with the high operating frequency and extraordinary performance that we received temperatures only increased to 68c under load. This is over 10 degrees Celsius cooler than both the reference Radeon HD 7970 and the NVIDIA GeForce GTX 680."

BF3 2560 X 1600 Ultra 4X MSAA
SAPPHIRE HD 7970 (1280) - avg 50.7 min 34 fps
ASUS GTX 680 (1291) - avg 51.3 min 30 fps

Batman AC 2560 X 1600 FXAA
SAPPHIRE HD 7970 (1280) - avg 62.2 min 36 fps
ASUS GTX 680 (1291) - avg 55.6 min 37 fps

The benchmark scenarios are same and the game patches are identical. so its a direct perf comparison. guess what your GTX 680 OC doesn't beat the HD 7970 OC . so the GTX 670 OC is not going to beat the HD 7970 OC biggrin.gif

I dont see the point on overclocking a 600 series nvidia card, this cards are boosting which is an overclock...

You cannot compare an erratic performance (boosting when allowed or depending of application and other factors) to a card that do 100% everytime that it is fire up dont matter the application or other factors..

But that is just me.... We are looking for performance not what ((if's)).. My 2 cents...
