Is there any 4870 1GB benchmarks? I cant find any and I see already these cards selling. Its very interesting to me what kind of advantage they have over the 4870 512MB and if they are getting closer to GTX280 performance
I have not seen anything on the 4870 1gb. Only the 4850 1gb, but no benchmarks to with those. I will tell you that if you play at very high resoluions then you can expect to see an increase in performance, but dont expect it to be substantial unless they change the clocks speeds along with the additional memory. The 1gb of memory is somewhat, for lack of a better term, "bottlenecked" by the 256bit width that the 48xx series architecture offers imo (I suppose I could be incorrect). Hope this helps.
