Well I'm thinking of going crossfire, before I do so I need two questions answering. 
1. I have a xfx 5870 now if I buy a HIS 5870 will I need to flash it to have xfx bios as I am wishing to OC to 1Ghz like my current card.
2. Is it worth me waiting for fermi release because i've heard prices arent going to drop although I'd be ****ed to buy it now and see that its £40 cheaper in a few weeks.
