(Going off-topic here, sorry, but there's no much more to say about the length of the R600)
I don't know about "Intel coming back" to the GPU market... Their onboard solutions suck for gaming, and the last Intel video card (real card) I remember is the i740. No one remembers that one, I wonder why... :roll:
My guess? Intel is going to do a serious "hit and miss".
I remember reading the issue of MaximumPC in which that card was published. I do believe the original had a Rive TNT2, Matrox G400, Voodoo3, S3 Virge, and Rage128 chip, though, and all that RAM added up to a now average 256MB.
