"The board's layout is well thought-out with very little to worry about around the CPU socket. We would like to see the same space around the second video card slot too, but that's a minor quibble that's not likely to be fixed on any motherboard. If you're looking to run SLI or CrossFire, you have to accept that your video subsystem is going to take up a considerable amount of space."
