70 per cent of upgrade market is still AGP
 

WE LEARNED that seventy per cent of upgrade market is still AGP. There are far too many people using AGP systems that will try to get the new graphic card for the Yule shopping madness. Nvidia just cannot fill the demand and is still struggling to get its 6800 GS AGP cards out while ATI is happy with its X800 GT, GTO, XL sales. Those cards are all native AGP but some of them can be bridged with the Rialto.
