It depends on how much memory you'll typically be using, and how.
The more memory you use for applications the less will be available for
cache. So you are more likely to hit cached files with more memory - this
will result in faster file accesses despite having slower RAM.
If you use so much that the system swaps regularly then any advantage of
the faster memory will be swamped by the delays in swapping.
A suggestion with no guarantee: If you expect to regularly use up to 300MB
for applications then 512MB of faster memory may be better. If you expect
to regularly use more than 300MB for applications then 768MB of slower
memory may be better.
This is a gut feel and is not based on a serious analysis.
A proper assessment of system performance is very indepth and requires
knowledge of the hardware and the expected uses of the machine.
I was assuming here that you're intending to use the system as a general
purpose workstation with a few services running (ie, a typical Linux box
accessing the net).
