j3pflynn, in my post I compared A64 with rating 3100 to P4 2.8 Ghz. AMD is too greedy with ratings, but the "advantage" in 300 points means that this chip will be at least as fast as P4 2.8 Ghz.
I don't think the exact speed matters for a business PC, what this HP desk is. The 3100 rating suggests that it will run Word and Excel better than the desktop they purchased in 1999 preparing for Y2K bug.
