crossfire 6950 question

[dean_b]

i am going to order 2 of these : http://www.overclockers.co.uk/showproduct.php?prodid=GX-042-HS

but i have a few questions
1) is it true some games wont register that there are 2 and only work on 1 ?
2) will they produce a lot of heat and so not last so long ?
3) are they good enough for ultra settings on games out now and also some in the future ?

thanks for any help

Why don't you wait for the new cards?

They are only a matter of week/s away, you could be getting faster performance while using less power and costing less.

Even if they were not to be released, the 6950's will still be there to buy

sorry for the late reply i've been sick but which card is coming out can you link me somewhere
thanks
