question about the multi gpu support

[deathclown]

if my mobo only support lets say an AMD crossfirex can i put a nvidia card or not ? my gut tells me that if ever it will work it will decrease  the performance of the card and another question does a 3-Way/2-Way AMD CrossFire™and 2-Way NVIDIA® SLI™ Technology support is different from NVIDIA® Quad-GPU SLI™ Technology and AMD Quad-GPU CrossFireX™ Technology support but still can i put either AMD or NVIDIA cards?

Nope, if you want to use 2 Nvidia cards, your motherboard must be SLI compatible.  Just because it is Xfire compatible doesn't mean SLI will work.

so if i have a geforce and it died and i bought an AMD in order for it work on the same mobo it should at least supports both sli and xfire ?

 

and if the mobo just supports SLI i should buy nvida and vice versa, correct?

[-rascal-]

SLI requires a minimum where the PCI-E slots runs at X8 speed electrically.

Crossfire(X) is a little less restrictive and will work with even PCI-E X4 speed.

Motherboards that have say... Have a PCI-E X16 slot and a PCI-E X4 slot... will automatically not qualify for SLI.

You can use nVidia graphics cards on a Crossfire(X) only capable board...but they can only run individually as two separate cards. This is goes for AMD cards on a SLI-only certified/capable motherboard.

A motherboard may be CrossfireX certified, but not SLI certified...and vice-versa.

Xfire and SLI are only when you use multiple GPUs at the same time.

 

You can switch between AMD to Nvidia if it is just 1 GPU that you are using.

1 GPU will work in any modern board,but SLI or crossfire differ

 

 

crossfireX is usually supported on most motherboards but SLI isnt

thanks for all the answers now i understand and yeah im just using 1 gpu im not into hardcore overkill build for gaming pc just mid-high end is enough for me
