Like the Gigabyte 890GPA-UD3H (also reviewed on the Asus Crosshair IV Formula is designed for Socket AM3 processors.

The Crosshair IV is flexible expansion-wise because it offers no less than four PCI-E x16 slots. You can use these to build a multi-GPU rig and because PCI-E x16 slots are backwards compatible with PCI-E x1, x4 and x8 devices, you can also fit other expansion cards.

If you have legacy cards the Crosshair also offers two PCI slots. The only issue here is that each PCI slot sits directly beneath the first and second PCI-E x16 slots. If you were to build a multi-GPU rig using two dual-slot GPUs, both PCI slots would become useless.

The Formula is future-proof packing 6Gb/s SATA and USB3.0 support. It also boasts an extremely tweak-friendly BIOS, every relevant overclocking setting is covered and the ranges on offer are massive and easily trump what the Gigabyte offers. The maximum CPU voltage offered by the Asus is 1.85volts to the Gigabyte's 1.75volts for example.

Performance-wise the Asus seemed more of a gaming motherboard as its World in Conflict and Street Fighter IV benchmark results were higher than the Gigabyte's figures. With Street Fighter IV the difference in figures was a massive 14fps. In terms of applications however the Asus finished at second place though the differences were minimal.

Verdict: If games and overclocking are your thing, the Asus is a well-rounded 890FX board to build your rig around.

Pros: Great MOBO, using it myself with a 1055 x6 the

Cons: You might need a pipe stack High Cooler sine the chipset heatpipe is a bit bulky on the board My Case is a thermaltake Element S so i had no problems but if you have a small ATX case with poor wiring sulutions... you might want to opt for a new case. another con is the lack of a PCI-E 1.0 slot,

Great Board overall and i seriously recommend for anyone whos a hardcore gamer/designer overclocking can be done either throught he bios or the asus Turbo Key suit in windows... what alos shocked me is how well UBUNTo recgnized the board and CPU almost right away after a small update. if you want to avoid overclocking and preserve your equipment on the long run i suggest going with 1800mhz ddr3 rams for good balanced performance.
