from what i've heard.. the G80 is going to be released much earlyer tough.. It's like comparing tha xbox360 and the ps3 imo.
As for the poll... I vote for the G80.. because its the pioneer of DX10 chips
the G80 might have something up it's sleeve.
I must say that things look really good for ATi at this point, but they are indeed a little late this time around and I'm looking forward to what the G80 could bring. Although I believe alot can be gained from waiting until both products are out and thoroughly compared before investing so much money in a new high end card. That way you make sure you get the best performance for the money and avoid later disappointment.
The Playstation 3 uses the NVIDIA RSX, based off of the G70.I vote for the R600...im waitin on it myself.
Its the PS3's video card on crack times 1200
I'm 100% with G80, because it will be released much earlier, and at the time ATI releases R600, nvidia will release G81.
