Sorry if this is the wrong place for this, but I couldnt find a more suitable forum.
I have a 790X-based mobo (specificaly the MSI K9A2-CF), and was considering installing a PCI-e SAS RAID card. However, the manual seems to indicate that installation of a second PCI-e card will knock both slots down to x8. Is this true? The SAS RAID cards I am looking at are 8x/4x, but I have a PCI-e Gfx card which I dont want to loose performance from (geforce 7800GT), so will do without if this is the case.
