I plan on buying the 3200+ (ClawHammer) and overclocking it to 220 fsb.
What I need to know now is what type of memory I should get.

I was originally planning on Crucial 184 Pin 512MB DDR PC-3200 8T:

But recently reconsidered for Corsair XMS Extreme Memory Speed Series 184 Pin 512MB DDR PC-3200C2PT:

So when there is a difference of $40 (per stick, I may get two), I have to wonder if it's really worth it.
I have no idea what timings I want, or how each specific model deals with the overclocked processor.

Suggestions for any other 512 sticks are welcome.

for overclocking you should go with the corsair over the crucial. I know ninja is gonna come in here and recommend some OCZ so if you find some similar OCZ you could look into that, although it will most likely cost a lot. between the crucial and the corsair definately go with the corsair for overclocking just make sure that your mobo will take it. My mobo (asus k8v se deluxe) would only accept like 20 kinds of memory so double check on that before purchasing.
