If you want to SLI two cards will i need to have the same model?

For example, i have an 8800GTX will i be able to SLI that with an 8800GT or will i need another 8800GTX?

Cheers.
 
The cards have to be the same model; it's not like CrossFire where you can mix and match cards from the same series.
 
i was under the impression that since the physx release you can run different cards as long as they are within a range eg the gtx280 can b in sli with the 8800gt and they will both run at their native speeds, but please correct me if im wrong
 
Nope you can only SLI cards with the same GPU core... 8800GT + 8800GTX is out and so is 8800GT + 200 series... also you really wouldn't want to SLI cards of mis-matched specs - thats one situation where you really would experience that "micro-stutter" thing...

It is theoretically possible to SLI 2 cards based on the G9x core i.e. 8800GT with 9800GTX but that requires monkeying about with the card(s) BIOS.
 
I think you can use one as a dedicated physx card, by not having the SLI bridge etc (correct me if im wrong). But to SLI they must be the same card ie 8800GTX x2
 
I`ll be hopefully going SLI next year but I don`t know how SLI works. I do know you need two cards and compatible SLI motherboard but then how do you get it working :o

I was wondering how do you plug both cards that are in SLI, into you LCD Screen? and ones both cards are into your motherboards PCI express slots, do they connect to each other somehow by using cables or something?

Thank you for responding.

I take it you get the 'bridge' connectors included in the box with the graphics card and then you only need to connect one of the cards into your LCD Screen?
Click to expand...

Bang both cards in, connect the SLi bridge internally, and connect your screen to an output on the card in the primary slot. Go into Windows, make sure it's enabled in the Nvidia CP....hey presto...multi-gpu.... :)
 
Unless things have changed, the SLI connectors come with the motherboards. about 6 months ago i bought an Nforce board, it came with an SLI bridge (along withe a gpu and RAM cooler =/), and the Nvidia card i put in didn't have one. It's the other way round with ATI, each card comes with a crossfire connector
