If anybody has a 900 series card , how does the new DSL technology work with XPX?

I am concernd about VRAM. Should i get the current 4GB ones or wait for 8GB cards to come out?

Depends on monitor size, resolution, settings and ADD-ONS. If you want max eye candy and you want to make it furture proof for a few years, I wouldn't get anything less then 6GB ! My 30" Dell monitor chews up almost 6GB of vram in XPX !
