Is this board good for SLI? "Only the top PCI-Express x16 slot operates at full speed, with the second and third slots dropping to x8 speeds if you try to install two graphics cards." Is it enough?

When you run SLI with two cards, you can only run in X8 X8 mode with the first two pcie x16 slots.
The motherboard is fine for Two way SLI. The motherboard is certified to be able to run two way SLI. That why in the specs, it will say it support Two Way SLI.
