Motherboard help

yes you can even though with the physx you won't see much difference. Some will say it is a wast of a GPU and others will say it helps. Bottom line it helps a little. If your card lets you use a Nvidia card and it supports crossfirex I would think you could SLI but both the cards have to be the same.

If you are worried about SLI then get a HD 6950 or 6970 then get another one down the line. But I am not 100% sure about SLI but I don't see anything that won't let you. Good luck on what you want to do.

you can sli any two of the same gpu from different manufactures like a asus gtx 560 amd gigabyte 560.
oh and nice motherboard by the way. and yes that would work

nooo you dont understand i have a non compatible sli motherboard it only accepts crossfire i wanna know if i can add a gtx 560 ti to the mix and use 460 as physx engine

Yes it should work

Yes you can. I tried to find some where that would tell me that it would support SLI and I can't find anything. It just tells us Crossfirex and Hybrid Tech nothing about SLI. You are good to go on your two GTX cards and good luck to ya and sorry for the confusion.
