Thanx for the quick responses. . The DFI UT P45-T2RS was also a candidate, but after reading the UT P45-T2RS thread and seeing Jor31BR comments about this board - the fact it has trouble running high clocks with quads - I'd made my choise.
I'll go for the UD3P (mainly because it's cheaper than the Extreme and is has LCC option in the bios, don't feel like modding the Extreme at the moment)
