Does anyone know which combination would provide best performance
and speed in AC12?
quad core at 3GHz or dual core at 3.33 GHz
and the other question would be the option of 8 GB ram @ 633 MHz Vs.
4 GB ram @ 800 MHz.
Thank you

4 GB of 800 MHz RAM should be better.

Thanks you guys,
Sense I wont be running two apps at the same time, sounds like the
quad core w/ 4 GB of the 800 MHz ram on 64bit vista ultimate would be
the best choice because AC won't utilize over 4GB of ram, right?

AC is a 32-bit application, 2 on the 32nd power is 4 billion, hence the 4 GB limit.

Right, and the system (windows) needs to be 64 bit in order to recognize, or allocate the 4GB to AC, even though AC is 32 bit. Do I have that correct?
I sure appriciate the help laszlonagy.
Thanks again

Let me correct myself a bit because Thomas is right: if you run AC under Vista 64-bit and you think AC will use 4 GB then there will not be any left for the system and some other programs you will inevitably run (mail, browser, Skype etc.) In that case 8GB sounds to be a better choice: 4 GB for AC, 4 GB for all the rest. Vista will probably need about 1 GB, plus the others.
