The reality is different actually. Biostar i45 can go 650 FSB and beyond. This is the cpu-z validation of a guy who has done a initial OC on this board which turned out to be 24/7 stable overclock:*valid.canardpc.com/cache/screenshot/434920.png

UD3P is a fantastic board. But the cost of it (in India) makes you think otherwise. Th northbridge heatsink is large and difficult to put some types of heatsinks, but I wouldnt managed that somehow.
Frankly speaking asus p5q series is supposed to be 1-1.5k cheaper even if one considers "exotic" pricing system over here.
