Hmm now the windows UI will be usable on DX9 if I read correctly. Well, I guess I'll get one 7800GT and wait till DX10 is out how well it runs. If it's ok then I'll nab another 7800GT, other wise I'll use the extra x16 slot and buy a DX10 card. Then I guess I'll have to dual boot XP and vista... least I'll be able to play old and new games from the same tower.
