Wow thank you for the very quick replys, and yes I knew it would involve some cutting (except it doesn't as my pcie 1x slot already has been cut to allow a 4x card to be used there, yes I realise the 6970 is getting quite old now and I could get a card pretty cheap that would out perform 2 of them, but I just don't have the money, I have been offered a second 6970 for £10 so thought I would ask if it was possible, and because I can't afford another motherboard, CPU ( because I have LGA 1155 and would update) and copy of windows ( because OEM windows ) I am stuck with one 16 x slot... Looks like I am going to get saving for a better card
