may have a point there. cranck the lot of options up, and this card could make the difference.

although, its still on a 2gb buffer per core, dont think each core can view,well,use,more than that..right brother sky?

In high bandwidth situations, yes. You can see the results of this at multi monitor resolutions with AA enabled.

?? I understand that the card is not actually drawing more power than available (unless you go past the 375w limit), but my thought was not that it's 'okay' but that it's not meeting actual specs? Yeah, it's hard to get access to full official specs at time... I assumed that the official spec of 300w meant that the TDP of the card couldn't exceed 300w. So, you're saying that there is a special rule that discusses PCIe cards that draw over 300w?

Does it really matter though? The 6990 isn't actually PCIe compliment certified anyways :)

Crossfire and SLI reviews will be done....before the release of any dual GPU cards are released from either camp.

SKY, how are those 6950 1GB in Xfire perform compared to 6950 2GB in xfire ? The XFX HD6950 1GB XXX cards were selling for $219 after MIR over at NCIX this week...that would make a nice gaming rig setup for 1080P for a few years right?

My question to the reviewer. Have you noticed any stutter in BFBC2 with Eyefinity with 6990 two gpu enabled? I'm sure it's stutters as hell since all AMD cards from 5 to 6 series having enormous stutter in crossfire + eyefinity, why you haven't described this issue? If you'll check widescreengaming forum every AMD crossfire user will confirm this problem - a lot of games stutters in crossfire + eyefinity.

I think the next generation - die shrink - as posted here previously AMD Expected to Launch New ATI GPU Generation in November | Hardware Canucks will provide improved performance and reduce power draw and thermals to make the GPU what AMD/ATi intended it to be during this release. If they had been able to release the 6990 with the die shrink it would have been an amazing product.

That's interesting since I actually play through a good section of the level and I really didn't notice it. Maybe it's only in certain portions of the game or only when framerates hit a specific point? I'll boot it up again tonight and take another look.

Please check this Widescreen Gaming Forum • View topic - Eyefinity + Crossfire = Stuttering
This is one of the many topics related to stutter problem on AMD cards with crossfire and eyefinity

I sold my second AMD card cuz of stutter. Stutter appears on 5970 too and if to disable second GPU it's dissappears.

Thumbs up Nice review as always..

Nice review as always, however, you did not touch in too much detail on the acoustics of the card. Any reasons for not providing the actual dB chart or did I just mis it?
