If it get two gtx 560ti's, one with 2gb of video memory, and the other with 1gb of video memory and i put them in SLI mode will i have 1gb, 2gb, or 3gb of video memory. Thank You.
Despite what some people think, sli memory does not scale. So yes you will have 1 gb total. The memory bandwidth in a way scales but both cards will be utilizing the same information mirrored.
