Why are there not many amd sli boards?

[liamcrane]

hi i have been looking around lots of sites and to me there is a real lack of amd sli boards, this is the first time i have used amd (spec in sig below) i have never used sli b4 but its something im interested in and reading a lot about thru the ocuk forums. I have a gigabyte 260 gtx i take it for the best performance it would be best getting the same card to avoid any issues, so really what im looking for is some advice on an sli board really, anything inparticular i should be looking for?

thanks again

Liam

makes sence really i guess, i have never really thought of sli, i dont really see the benifits of it imo apart from costing you an arm and a leg!! i mean i ran crysis on my phenom II at stock 3.2 with max settings and had a stable steady 30fps with my single 260gtx, towards the end it went a bit funny but crysis is a pc'c worst nightmare anyway! if i can run a game of that graphical intail with smooth gameplay why would i want to add another card which then uses more power which produces more heat, seems silly to me anyway
