Graphic artist and photographer: I needed a board to upgrade my 3D graphics station to 64 bit. It accepts 32 or 64 bit processors and has hyperthreading. The variety of processors this board accepts makes it versatile, although the initial set-up saw the chip running only at half speed. The chip multiplier in the bios had defaulted to half the required ratio and was easily corrected through settings. The 4 memory slots (all DDR2) allows a maximum of 16Gb, so 4 x 2Gb gives the option of 2 matching pairs in 'dual channel' mode. 4Gb memory being considerably more expensive than 2Gb, this allows me to add 8Gb without becoming destitute!
The board is designed for overclocking the processor with plenty of options in the bios, and has a utility on the accompanying CD to test the speed before making the change permanent in the settings.
It has been such a useful upgrade for my 3D production machine, that, given the decent price, I bought another for my photographic workstation!
