KeithDust2000, I just posted on that. I said I beleive AGP implementation is so different from classic northbridge, that it's not ready yet. Just doesn't work fast so far.
Or you're asking why 2 Ghz will not help? Because I'm convinced that Athlon 64 and Opteron are very good performers. If I see bad 3D score, I imagine AGP is a problem. If you put faster cpu, it doesn't matter. And what do you think?
