Wasnt the HD4xxx series surrounded by the same rumours?

Oh it will only have 640 stream processors as the flag ship as its double what they have been doing the past two generations

HD2900 = 320
HD3870 = 320
Assumed HD4870 = 640
Actual HD4870 = 800



So i say lets wait a little bit longer as i can see there being either a memory boost to the chip e.g 384 or maybe a return to 512 ring bus?

Or a dramatic improvement in tessalation in a response to nvidias domination
