Recommendations on Gigabyte's GA-G33M-DS2R

I plan to upgrade my system with either Gigabyte's GA-G33M-DS2R or
Asus P5K-VM to be coupled with an E6550 and DDR2 1066 Ram
(Corsair Dual Channel TWINX 2048MB PC8500 DDR2 1066MHz E.P.P. Memory -
OR - Crucial Ballistix Dual Channel 2048MB PC8500 DDR2 1066MHz
Memory), the OS will be either XP SP2 or Server2003.

I am not to interested on OC this mobo/cpu combo (at least for
now.. )

1) I wondered if anyone encountered any issues running when running
the GA-G33M-DS2R with a E6550 at 1300 FSB while using DDR2 1066MHz?

2) Between Gigabyte's GA-G33M-DS2R or Asus P5K-VM - Which mobo would
you recommend?
