7950 Crossfire vs 680 SLI at 5760*1080 (Eyefinity/Surround)

@ Rusty, Your GPU temps.

If one is running a bit to warm it could be because your picking up the hot air from the other in xFire.

I think you had closed pull push GTX 680's? they blow the hot air out the back of the case, if you want the same thing with AMD you need to get one with the reference cooler or the IceQ one. others do dump hot air into the case, one will suck in the hot air from the other if they are close together.

Failing that turn your intake and exhaust fans up to create more airflow.

Thanks humbug I am aware of how it works :D.

The hot card runs at 85c full blast with crossfire disabled so it's knackered. I would expect it to heat up by 5-10c with crossfire enabled which it does, it just heats up to 91-95c :D.

The other card in the same scenario (crossfire disabled) runs at 65-75c depending on the overclock. (1150 vs 1250)

I think I said it a while back but I haven't got a hope of getting above 1150 on the hot card. So like for like, it's a cool 20c hotter :(

The more I read this thread the more I wish I could go with dual 7970s, but I keep thinking about the reports of issues with corssfire on Rampage IV boards (on ROG forums).

Seems like I'd be better off getting 670s and keeping my current board than getting a new motherboard and 2 7970s.

It is very tempting though, just awaiting the big but...
 
Rusty, I am sorry for the disagreement we had.
I only did exactly what you have done.
I thought it made good sense to swap my GTX 470 SLi rig for a fantastic value HD 7950.
I agree also that I got a bad HD 7950

I do not regret going back to nVidia as my GTX 660 Ti cost exactly what my HD 7950 did and performs flawlessly at my resolution 1080p

The regret I have is the price I paid for my card. I really wanted a GTX 670 but at the time they were £300+

Please tell us what the big 'But' is!

And thanks for taking the time and trouble to do this.

your knowledge is pretty extensive, i know :)

just throwing another possibility at you, one which you 'yet' might not have thought about.
