Here's a Crysis 2 one. 60fps at stock speeds and the 67fps is at 1100/1575 with the AB showing both benches with GPU usage around 65%

Here's the Crysis 1. GPU usage on both is only 75% and ran at stock 925/1375 speeds.

These numbers seem a low and same with GPU usage. I doubt my 2600k at 4.5ghz is the choke point for two 7970s....I ran a Crysis 1 bench with 1 card at 1100/1575 and netted me 56fps with 95%~ GPU usage. I am on RC11, are these numbers right?
***Edit:
Just realized my Crysis 2 bench was ran at the lowest "High" settings so I reran it with Ultra @ 1100/1575:
crysis2benchultra.png
Same results from Ultra/High settings at 1100/1575 @ 67fps~ with GPU usage floating around 65%

Just ran mine at your settings at stock (1070MHz with my Lightnings) and noticed the same kind of GPU usage you were getting (~75%). I guess this is just more driver issues with the 7970's. Even still, my score was just about 7fps higher at stock than my 580 Lightnings were at max OC...

Wow, you're the first I've seen go to the 7970 from the 680. I wasn't aware there was a stuttering issue with the 680's?
post #9955 of 38701
Hi, I bought 7970s at release and also 680 sli at release. Have a pretty good idea of which one does what better, it is generally application specific. The 7970s are definitely better in crysis 1/2/WH in terms of framerates, I play at 2560 resolution with everything maxed. Also, with RC11 drivers there is a bug where your GPU usage goes awry when you switch from windowed mode with alt enter to full screen. Or should I say, if you go to windowed mode and switch back to full screen your GPU usage goes up. This only happens with RC11...it was weird, not sure how to explain it. Anyway, whoever did that crysis test, upgrade your drivers. 11.2 is horrible with GPU usage in crossfire, I had the same issues with RC11 at release.

Once I upgraded to 12.x everything was fine, really, the 12.x WHQL's are far better with GPU usage in crossfire. 12.4 WHQL has been really solid on my 7970 box as well.

Well I am back from basic and in tech school. Waiting to get my computer somehow. That said I am sad to see he 7970s beat and sad that they dropped 75$ in 3 months

Anyways . How are the drivers now for say skyrim? Was getting a lot of stuttering score I shipped out has that been fixed ?

Don't want to go off topic but here you go:

Anyway I ran a 7970, then got a 2nd...then drivers drove me mad so jumped on the GTX680 bus and I regret it.

Its not so clear cut. At maximum overclocks for both cards, they are even, and the 7970 wins many titles. If you compare stock clocks then yes, the 680 wins, but once you overclock the advantage goes away completely.

http://hardocp.com/article/2012/04/10/sapphire_hd_7970_oc_edition_video_card_review/

There you can see the 7970 OC basically decimate a stock 680. So don't fret too much. The 680 isn't by any means a bad card, it is awesome, but IMO it does not scale as well with overclocks as does the 7970.

Also: I see you joined the air force, lol. Why didn't you join a branch for real men? I kid wink.gif I was in the Marines side of the house and both Army and Marines are always jealous, if not completely hating on airmen because you guys have it GOOD compared to us. A LOT BETTER. I was stationed at Camp Lejeune and air force guys stationed there get substandard housing pay ... because apparently our facilities are run down compared to AF. lol.

Wow, hadn't heard about that over in the 680 Club. I'm planning on jumping ship to 680 Lightnings when they release simply for the superior drivers and support. That forum link you posted had an Nvidia Tech Support guy responding to the original complaint within ten minutes! Try getting anybody from AMD to respond to a complaint at all...
post #9960 of 38701
Bro sell me one of your 7970 lightnings! I was a big fan of the 580 lightnings, I can't find the 7970 lightning for sale anywhere though.
