hi guy , im newbie so forgive if my questions are so stupid Currently im running 2 4870x2 CF with mobo Asus m3a32 mpv deluxe and pIIx4 965be 8gh ddr2 ram I love to have the tessellation feature but AMD seem wont enable for radeon4000 due to hardware limitation and my 2 4870x2 still very strong . My question is can i use the type of configuration like: 4870x2 CF + radeon6000(low profile cards) to activate tessellation This idea is similar like AMD + NVIDIA for PhysX in past. But it will not be limited by drivers. My understanding is radeon4000 has the tessellation unit but it's weaker than the demand of DX11. If this idea can be done, it will give people who have low budget like me a chance to live in game world Again, please forgive my English (is my second language) and my questions if they are so dummy.
