P4 2.66GHz/L2 512k/400MHz Vs. P4 2.6GHz/L2 512k/800MHz

[psychy]

Can anyone tell me between these two chips:

P4 2.66GHz, L2 512k, 400MHz
&
P4 2.6GHz, L2 512k, 800MHz

Which is the better performer from stock? Or very very slighty OC'ed via voltage increase?

Reason being, i have both chips but dunno which to use in my SFF.

Thanks
Steve
