money is not object but what video cards should i get

out of these two setups which setup is better

2 radeon hd vapor x 5770 crossfired 0r

2 radeon hd vapor x 4890 crossfire

and the only reason i am asking because is there an advantage to have direct x 11 now or wil 4890 also perform well with direct x 11 games even though they are only direct x 10

cost is about the same though combos on newegg

why would u say only get 1 5770

u have a good point i might just get the 5850
