This board is an update on the SL75KV since the old board there has been 2 major changes to the board, the first that I spotted after about 2 seconds of looking at the board was that of Dipswitches. These allow the adjustment of the multiplier on the CPU. The SL75KV used the KT133 chipset and it still has the AGP Pro, which was on this board, however, this board has only one serial port, but there is an extra external serial port, which can plug in to the motherboard. But not everyone needs this I only use on Serial port.
Another thing which Soltek haven't done nor did Abit and I missed this and this was the 4 Dimm slots, it only has 3 even though the KT133 chipset supports it, so in theory you can have 1.5GB of ram if you are that power mad
