I'm looking to buy another 5770 to go into crossfire. Currently i have the vapour X version. However that has gone up in price, would i be able to stick http://www.overclockers.co.uk/showproduct.php?prodid=GX-019-C3&groupid=701&catid=56&subcat=1515 along side my vapour X? I know i need two of the same card but do they have to exactly match?

They don't have to be the same brand, e.g. Sapphire with another Sapphire. You could have Sapphire with Asus for example.
