23,806 Graphics Score in Cross-Fire.
CPU is an FX one. Whether that affect the score or not, I don't know.
This video is now marked private, but I was able to watch most of it before that happened.
These don't seem like the most professional reviewers. I couldn't understand the language, but there was a lot of fumbling around and it doesn't look like this "presentation" was rehearsed at all.
The video notes indicate that both 4GB and 8GB versions were tested (can't get the exact wording now that it's private). Does that mean they set them up in CrossFire where one card was 4GB and the other was 8GB? Is that even a supported configuration?
AMD needs to have rock-stable drivers on Day 1. Bad launch drivers have caused too many problems in the past, and as the saying goes, you never get a second chance to make a first impression. Even if they're fixed afterward, the stigma will remain. That said, as noted above, I don't give much stock to this particular YouTube video. If we see driver crashes observed by reputable sites on launch day,
that is cause for serious concern.
