My theory is that my 2nd 6990 wasn't getting enough juice when there was heavy crossfire gpu usage, hence the no video display error whenever there was heavy action. I'm a happy camper. Thank you Ken.thumb.gif

Wow a cable extention was the problem?

Crazy how much trouble that caused:p But thanks for pointing that out as I can see something weird like this happening to me also. I use extentions on my cards too.

The cable extension was a snug fit and I assume throughout the many months of usage, the cable extension got tugged and the cables inside it got stretched and started to lose connection. I found longer 8-pin extension cables and I make sure there is more than enough slack that it doesn't get tugged in the long run.

I once lost countless hours troubleshooting an Nvidia 8800 back in the days... sigh... My brand new Enermax Galaxy 1000w PSU had a defective 8 pins PCI cable...

It took me hours to find that. frown.gif

Hey guys, are 6990 going to be obsolete when the 7970 comes out? Or will it stay top dog for another year? If not I might sell mine now.

What do you mean "obselete"? The new dual gpu will be 7990 and that will be released 3-6 months after the release of 7970. Seeing the 5970 was slightly faster than a 6970, I'm sure the 6990 will be slightly faster than a 7970.

Having your top dog card fall to second or third place is hardly grounds for calling it obsolete. If you need more power, upgrade. If it's letting you do what you want to do, keep it. But if you are going to upgrade somewhere down the line anyway and you have a habit of selling old parts, then it will sell for more the sooner you sell it.
