Since sandy bridge is on slot LG 1155 i think i might just wait for them.
However since i wont be upgrading for 3+ years, would it be better to go with tthe PhenomII X6 1090T?
I know the Intel cpus are way better atm, and will probally be better in the new ones, so it would probally be best just go to with sandy bridge?
What would you be using this processor for? For gaming, Sandy Bridge (pick one) will smoke a six core Phenom II. I forget if I've seen the Phenom II X6 (any) against any of the SB chips in any earlier preview stuff, but I'm pretty sure Sandy Bridge will still be better.
BTW, I was going to get an i5-760 but I decided to wait for Sandy Bridge. They're more powerful clock for clock than the current i-series and have some pretty high clock frequencies to boot. As you said, you won't be upgrading another 3+ years, so I think you'd be better off waiting a month.
