I do to this day believe the GTX 280 has more bandwith than it needs. This is why high core overclocks of the GTX 260 make it so easily caught up with the GTX 280.
I agree. As I've said several times before, pixel fill rate (and even memory bandwidth to an extent) hasn't gotten much attention since we started seeing unified shaders. Everyone talks about the SPs and the shader clock but a ton of fillrate is still going to make for a faster graphics card where as 10 billion shader processors is only going to do as much shader processing as is required.
We haven't yet reached the point where everything can be done with shaders. 1920x1200 with 8xAA in a game with extremely high res textures, foliage and a huge draw distance is still going to bring a huge fill rate load on the GPU, no matter how many SPs it has.
