Dual 680 or single 690?

Pros:
- Cheaper as 680s are 400 GBP each meeting 800 GBP for both (almost 100 extra for 690)
- Airflow blows in one direction out the back of the PCI expansion slot grilles whereas the 690 blows the front side GPU heat back into the case....BAD Nvidia!

Cons:
- Higher power consumption, 195Watts as a max in each 680, so total 390Watts (300Watts for 690 for whole card)
- Tighter space for airflow capability and obligation to re-position sound cards possibly to a lower slot.
- 690 is more aesthetically presentable (negligible point lol)

Can you assign phys X and similar SLI functions to each GPU as if they were separate cards? (I am assuming so as it is simply another SLI bridge but printed onto the board itself instead)

Please post if you believe you have relevant feedback that people ACTUALLY WANT TO READ. Don't turn this into a trolling thread with useless text.

Cheers

Ok I'll reply you shortly before this thread gets too much ridiculous comments, it's always easy to spend people's money.

Since you can't find either a GTX 680 for $500 or GTX 690 for $1000 your best option now is to grab a dual GTX 670s in SLI, they consumes less power, almost as fast as GTX 680, will give you the same results of GTX 690 and will run much cooler than GTX 680s in SLI.

You don't need to assign a dedicated Physx card, first of all a single GTX 680/670 is already overkill for any Physx game around.
Second, only few games that support Accelerated GPU Physx such as Metro 2033, Mafia II & B.AC. And 2 cards on SLI are already overkill.

I'd rather get 2 GTX 670s and save yourself a lot of money.

Actually go with 1 GTX 670 and see how you fair, they are powerful cards and might be enough on its own without the need for another.

Also what resolution/PSU?

Because the 690 has two gpu's and you can put them in SLI then in the Nvidia control panel it will show the same as two gpu's because you don't have to run the card in SLI it's an option to do so. The benefit of the 690 is that you can use just the one slot vs two slots with the 680's , however I think I would want a Pci-e 3.0 slot for the 690. I haven't seen any benchmarks where they took a 690 and put it in the two different slots to see if it made any difference. I know that you need the three components to be Pci-e 3.0 and with Ivy Bridge just being released I'm hopeing that these sites get around to testing the 690 in the 3.0 slot vs the 2.1 slot.
For now though I would prefer the two GTX 670's as it stands with what's been released. I think that Nvidia is up to something because they just released the 670 and the benchmarks that I have seen shows that the card is capable of keeping up with a 680 and two 670's in SLI have the same fps as two 680's in SLI and the 690. So unless Nvidia is losing its mind somethings up.

So untill Nvidia puts out something else that makes sense I'm going with two 670's in SLI because for less money you can get the same performance as two 680's in SLI and forget the 690 as well. Right now the 670 is going for around $400 , the 680 for around $500 and the 690 for $1000 , so for $800 i can get the same performance as the 690 at $1000. Does this make any sense ??

Are you sure your not trolling? There are so many threads that are more like a manifesto than a question, lol. peace!
