Yea the x2 doesn't do anything for me in regards to gaming (or very little anyway...), and sometimes hurts it. And that 7800 series is awesome. Right this second i don't even have both 6800's in, and at the same settings i'm now lagging a bit in cs (relatively...i can visibly notice a difference when i turn quickly...). I only have one in because i was trying to put my new hs's on those cards one at a time...but it turned out they didn't fit, and after a flurry of emails and pictures, i have a new set on the way, and my 6800 now sits without a hs on my desk at home.
In most bench's that 7800 high end (gt? or gtx...?) is just awesome. I had a funny look on my face when i read that last week...I think i was mouthing "Dammit"...then "time to overclock those bitches". Heh. But as is, they're overheating not oc'd at all. Hitting 90c. I've got a 120mm fan blowing out from over those two cards, because it was doing worse with it blowing on to it. =/ The hs should help some, but really it's an issue with air not circulating right. I've got an ungodly amount of fans in this machine, but it just isn't circulating. I think maybe i need to drill some holes in the bottom or something...maybe put another fan or two down there.
Basically when you have two cards...2-3 inches apart...both running anywhere from 50-90c, not to mention the chipset fan running 45c between the two, you get a very hot spot. Also, there is a fraction of an inch, between the cards and the hds...so air is cut off all the way across the case. I have a 80 blowing across the hd's out on to one of the gpus, and one directly below it blowing air in...so there ARE fans there...just not enough to make a difference. The side fan (120) blows hot air out, the two on top blow warm air out, 2 80s in back blow air on to the cpu, 2 in the psu blow out, 2 in the front blow in. Shew...the tornado on my xp90 and the 3 120s are on a fan controller. I have a wattage tester plugged in to the power coming out of the computer and while gaming i'm pulling about 210w, 222w with the tornado all the way up, 225w with all 4 fans all the way up. I haven't gotten to test that thing with the other 6800 in yet though. I'm pretty curious how much putting that one in would pull. That said, i only pull 130w when everything is just sitting there, and only 160w when i have just the two core's maxed. (obviously when gaming i'm only maxing one core...)
