Trade in 6990 for 7970

I have the chance of selling my 6990 and getting a 7970 (Specificaly this 7970 http://www.gigabyte.com/products/product-page.aspx?pid=4290#ov)

I haven't seen many benchmarks at 5760x1080 so I don't know which would be faster, I assume the will be close.

One advantage I see is MUCH less heat output. but is that worth the trouble any money for a 7970. I'm not interested on waiting for GTX780 or 8970 cause they will most likely be $500+.
 
I would do it. 1100mhz HD7970 should be as fast or faster than HD6990 on average.

At 1.05ghz, HD7970 is already faster than 6990 is at 2560x1600. Can't see HD6990 being much better at 5760x1080.

Alternatively, if you don't mind cross-fire, you could consider going for 2x HD7950s and overclocking them. That would give you more bang for the buck than a $450 1100mhz Gigabyte 7970.

A single GPU (HD7970 1100mhz) to me is preferable over dual-GPU card (HD6990) since it takes time for cross-fire profiles to be released to support the latest games.

Look at Dishonored or Of Orcs and Men - CF/SLI often don't work on newer games for a while.

If you have ATI on your system already CCC drivers etc. Then you take it out and put in a nVidia card I can almost guarantee you problems like BSOD etc etc.

You need to do a clean format if you decide to switch to nVidia.

IMO, stick with ATI and what you got performance is same and you don't have to format and reinstall everything. gl
 
In my experience, one card is almost always a smoother experience overall than crossfire. I would opt for the 7970. I went from crossfired 6970's to a 670, and things are a lot smoother.
 
OH MY BAD, their both ATI cards.

Sorry. Yes do the upgrade or sidegrade.. and OC the heck out of it.

Varies system by system. I had 2 6950's , did an express uninstall via ccc, then manually removed the remaining registry keys and folders in safe mode. I then upgraded to sli 670's and installed nvidias latest drivers, no problems at All. Took about 20 minutes max.

If you plan to go with a nvidia, they are quite cheap atm.
