The question now is how does the added bandwidth of the GDDR5 directly affect performance? Based off the initial reviews I've read, it doesn't look to be as much of a factor as I had suspected it would be based off of the relatively low performance gaps at high resolutions....

It seems that without AA, the gap is larger, showing the increase in bandwidth. As soon as you introduce AA, however, the gap shrinks as the bottleneck shifts back to math.

Keep in mind that 4870's default clock is 20% higher than the 50s... Thoughts?
