Starting with 8x series of drivers there will be some needed additions -
1) SLI switching on the fly.
2) Optimisations for AMD64 X2 'dual cores'.
3) No longer tied to same manufacturers boards
4) Independent overclocking of boards.
Could be possibly what omegadrivers.net are reffering to when saying they might have something this week. Although my bet is that they will be based on 77.62.
