Gigabyte's GA-MA790FXT-UD5P motherboard is based on the AMD 790FX and SB750 chipsets and offers up much in the way of dual videocard gaming and generally fast socket AM3 AMD processor support. At its heart is AMDs 790FX chipset which supports HyperTransport 3.0 at 5200 MT/S. The Gigabyte GA-MA790FXT-UD5P supports DDR3 memory at speeds of up to 1066/1333MHz, and 1666 MHz when overclocked.
Discrete videocards are handled by a pair of PCI Express 2.0 x16 slots, and since the AMD 790FX forms the basis of the 'Dragon Platform' you can bet AMD Crossfire X is supported. Additional expansion is taken care of by three PCI Express x1 slots and two PCI slots. Unlike the AMD 790GX, the 790FX does not include the Radeon HD 3300 integrated graphics.
For those who are building high-end Phenom II systems, this likely won't be a large loss since discrete graphics will always outperform IGPs.
