Thanks for the replies, and reference to the GA-X38T-DQ6 info.
I like the GB X38/38T as they support the 45nm CPU's for future upgrades (I have a Q6600 at the moment). I primarily run Flight Sim X which is largely CPU-bound, hence my interest in these boards. How much of a performance limiter would DDR2 be on what we know about the 45nm CPU's?
Also- are DDR2 and DDR3 always mutually exclusive on other X38 boards?
Thanks- Bruce.
