Should I get a MSI Turbo-R?

[trilobyte]

Right now i'm using a MSI K7Tpro2-A and a 1ghz T-Bird. I was planning on waiting for the dual tbird mobos to come out but it's looking more and more like that's not going to happen. Should I drop the ball and get a kt133a chipset? How long do you think this 266bus will last before AMD changes their chip and makes everyone buy new boards...again?

BTW I here that the new beta bios of the turbo suppors 4-way interleaving. What is this and how would i use it?

Thanks
