Dunno mate, I don't have the MF II, but next week my mate will have his 2 4870 cards and he will test them on his P5Q dlx, hopefully he can deliver us some good news that the Tweaktown review was a bit over the top... I like my board with a single card solution... totally amasing to me... P5K Dlx revisited for me...easy setup and reliability... and coming from an Nvidia mobo you will be pleasantly surprised
