What's also interesting to note is that if you extrapolate based on this data then you'll see that the forthcoming generation of GPUs will need even more powerful processors than an Athlon XP 2100+ in order to get the most out of their performance. With AMD slowly ramping the clock speed of the Athlon XP line between now and Hammer's release, it looks like we'll be testing R300 and NV30 on Pentium 4 systems.
