Recommendations for an Asus K8V?

[Traxx]

Of course, I should just go with PC3200.

However, I change my system configuration more often than my memory (I've used the same PC2100 DDR since the Athlon T-Bird days), which prompts me to think more towards the future. Is there any preformance difference in getting faster ram (PC3500, 3700, etc), even though ideally, I should just use PC3200? I know memory can clock down to its proper settings, I just need to know if it's worth it to spend the extra cash if I won't see the difference, or if its less stable. Should I get the faster RAM, even though I may see little out of it?

I notice a difference between DDR400 and DDR266 ram.

In Emperor: Battle for Dune you scroll much slower with the lower speed RAM.

EDIT: For everything else, I don't notice at all! Though benchmarks shows a dramatic drop in system performance scores across the board.
