tominator006 :
can one of yall explain to me exactly what "true" sli is? like i have an MSI gtx 560 and if i get this asrock board could i get another gtx 560 and run them in sli?
SLi is just running two GPUs. PCI-E lanes had bandwidth. The bigger the bandwidth, the more information can travel through it. It is like a road. you have a road that is a 16x, but now you need two roads (for two cards), so some boards will just add another 4x road (which can make you lose performance because it cannot take all the data you want to run through it), but then some split into two 8x roads like the ASROCK board does. 8x is more than enough "road space" to handle any single GPU card.
Also, if you ever get an IB CPU, you will have PCI-E 3.0, which doubles the bandwidth.
What I am trying to get at if it didn't make sense is, you are fine with the ASROCK.
