For gaming, which clock speed is more important, core or memory?

Take for instance the 5900 sp version by msi (not ultra, see other post in this forum for more details about sp card). My card is currently running at 468/823 for core and memory. This compares to 400/850 for the 128 mb non-ultra 5900.

Which card would be faster in most games? I'm assuming the core speed is more important since the ultra card runs at 450/850 (hence core 50 mhz faster vs non-ultra).

i beleive the core helps with shaders/geometry (ala DX9/Halo)
and the memory helps with Anisotropic Filtering/ Anti-Aliasing.

However i may be talking rubbish. And dont forget the higher cards also overclock. (who runs a 5900Ultra at standard speeds???!!) Mines at 525/950...

Both are very important.

The core will be more important in geometry heavy titles or titles making heavy use of shaders.

The memory will be more important in fillrate limited titles, or if AA and ansio are used.

Well if you plan on doing filtering then you may wanna focus on the memory a bit more. Other than that hit on the core.
