The GA-X58A-UD9 is Gigabyte's flagship X58 board and it sports a price tag of US $649. For that mighty price you get a LGA 1366 board that can run four GPUs simultaneously and packs 6Gb/sec Serial ATA support.

The board is able to run a four-way multi-GPU setup thanks to no less than seven PCI-E x16 expansion slots, four of which can run in x16 mode. These four slots should be used when building a multi-GPU system as they will provide maximum bandwidth for the bandwidth-hungry graphics cards. The remaining three PCI-E x16 slots run at x8 mode and so can be populated by other expansion cards.
   
Despite the board's feature-rich nature it still sports a clean, useable layout thanks to its XL-ATX form factor. You'll need a fairly large case to house the motherboard however, as it measures 345 x 262mm. The UD9's BIOS offers plenty of overclocking options, so you will be able to push your components to their very limits.

The GA-X58A-UD9 outperformed every other X58 board we've tested in our benchmarks by small margins. We were able to build a quad-GTX 470 setup but here performance didn't quite blow us away. This isn't the Gigabyte's fault however as multi-GPU technology, has always returned iffy graphics performance.

Verdict: A pricey board but if you’re building a monster PC its features and performance make it worth the price.
