Two Graphics Cards?

I think i've seen somewhere that you can connect two graphics cards together to work in parallel. Dramatically increase your graphics capabilities, or something.

Is there truth in this? If so, any good articles? Links? How-To's?

Yes this is true. It's called Dual GPU and Nvidia and all the other top bidio card companies are trying to get at it. I would think because of the new physics processing chip that is coming out. Look it up on Wikipedia!

While we're talking about parallel-linking gfx cards .. on the new mobo's are all the PCI slots PCIx? Or would you have to buy a board that specifically comes with two video card slots?

I call it waste of money on PCI Express. Today's graphic cards are good enough, and if a 6600 isn't fast enough, get a 6800. By the time it's slow and you want more, two 6800 won't be a desirable solution, as there'll be new shader models and features in newer cards which you also want, besides raw speed. So no, it's not a good idea, it's a waste of money.

Wrong.  It's called SLI.  Dual GPUs is something different (and will probably be implemented better).

I think it's cool, as you can get one card, and then at some point in the future add another card...

Think again. You need identical cards and often identical firmwares. There's no guarantee that even if you buy the same model of card at some later date that it will be identical to the earlier one (manufacturers often make revisions), which could cause you problems. It's better to buy them both at the same time.

And today's cards power is more than enough. If you want more, don't get two 6600s, get one 6800. By the time the 6800 is not enough, you don't want another 6800 for more brute power. You want a new card which implements the new shader models and effects.

SLI is useless. Just there to catch lusers.

SLI was ment to be used with 3d editing programs like 3d max or maya. It was never intended to run, not very good at running your Quake 4 game on 'OMG EYECANDY' mode.

>>9
So why is SLI mostly found in consumer cards then?

Marketing

is it true that SLI does't work with dual monitors?

>>12
Yes. You can't connect one monitor to each card, because they're both being used to generate a single image.

>>10
Consumer cards? There was SLI-type support for graphic cards way before SLI came out, and they always have been highend graphic cards. They cost a small fortume and they never had support for DirectX whatever. They are so powerful they would fuck your game up the ass and beat it across the fucking earth because it is not worthy of such a beautiful piece of hardware. http://www.theinquirer.net/?article=12599

And there is one that I heard about, but could never find that could link up to 6(?) of the same type graphic card up for extreme polygon and texture rendering in 3dmax or whatever (Pixar highend rendering)

I am sorry, ignore that last link, I was drunk when I posted all this and didn't gather all my information. I appologize.

wrong.
