Why are you all happy and giddy that 580 SLI (1000$) beats a 6990 (700$)? LOL! 1000$ agianst 700$. Seriously.
The real competiton for 580 SLI is 6990+6970 in Tri-Fire, 1000$ against 1000$. I'm not alone thinking that. Here's what Brent the 6990 reviewer at HardOCP had to say about the subject:
''During the second day of testing 6990 near launch time, it hit me that Tri-Fire is really the competition for 580 SLI and that we need to test it.
So it has always been on our minds, since before launch, to test Tri-Fire. We will get to it''
And with early beta drivers, a 6990+6970 is already raping 580 1.5gb SLI. Just search for those reviews. I have already post them.
And you don't see the fanboys who said I was wrong and ''FAIL so HARD, 3 GPUs agianst 2 GPUs! blah blah blah'' in HHardOCP flame someone from the staff. No. Too afraid to get banned. Bunch of little girls hidding behind a keyboard.
Accept it. 6990+6970 IS 580 SLI 1.5gb competition, and it's simply raping it.
''Deal with it'' (imagine a gigantic childish dog taking half a page in lame 8 bits wearing black glasses in here).
