Its funny how you low end guys are always running your mouth about high-end hardware when you have zero experience with it. I picked up my 690 over a year ago and I'm very pleased with it. I have had zero issues with mine. Runs cool and very strong. Perfect for 2560 gaming. As others have mentioned 2560 is not for everyone. In order to experience it properly you will need at least a pair of 670's or better. If your running it with a single 680/7970 at cut down settings your doing it wrong.
Oh man, you're so right. In fact, I have no place to talk about things I don't own. I'm just going to leave the entire Internet now.
Tell me, how much did that 690 cost? $1000 sounds about right. I could be wrong, but they've stayed mostly static in price from what I can tell. We can agree that 680s cost about $400, correct? Maybe you got a good deal, I don't know. But a 690 is a dual GPU with about the same performance as SLIed 680s. Fact. A 590 is a dual GPU with the same performance as SLIed 580s. Also a fact. Therefore, a hypothetical 790 would be the same as SLIed 780s. We can agree on this, yes?
Now, my question is one of practicality. Assuming price trends continue, a 790 would cost more than a pair of 780s - perhaps $1500. The 690 is $1000 and a 680, depending on the brand, is $400. Until last month, a 7990 was also $1000 and 7970s were around $400, again, depending on the brand or model (GHz edition, better cooler, MOAR RAM). Why would I spend more money to get the same or less performance? Crossfire and SLI work just as well for a lower cost.
And finally, why would you want a dual GPU in the first place? They get hot quickly compared to the alternatives, given that you have two GPUs outputting heat on the same chip to the same cooler. They have, at best, equivalent to PCIe x8 bandwidth. That's not a huge performance loss (a few percent) but should certainly be mentioned given the alternatives. As said earlier, they're the best solution for mITX. But if the rig will be static, mATX or bigger supports traditional crossfire/SLI. If the rig will be mobile, then why are you spending so much money on performance you won't need? Your 27" 1440p monitor is NOT mobile by any reasonable definition. And above all, they just don't sell well. Why focus your resources on a very, very niche product that won't sell when you can work on relatively mainstream ones that will?
