There was a lot of misinformation in the vj's last post. I'll try to correct:
Multiple graphics card usage for anything other than more display outputs requires OS support (only from windows at the moment), as well as a motherboard that supports it for Nvidia's SLI, whereas ATI's crossfire just requires an interconnect for both cards.
Final Cut Pro is not optimized to make usage of extra graphics card resources, so VRAM is largely irrelevant to it. It is far more important in Motion. All the Apple apps have LIMITED multicore support, meaning most can use anywhere from 2-4 cores at once, depending on activity. Encoding (not rendering in Final Cut) can use all of your available cores at once if properly configured.
Final Cut Pro and all other 32-bit apps cannot use more than 4 GB of RAM. But newer apps such as Motion can use more than 4 GB of RAM, and more is of course better. It also helps if you want to run multiple applications at once.
This is all only relevant if you really know your craft well and how to get the most use out of your machine. If you do not, a much simpler solution will suffice and you are essentially wasting money on resources you will not use.
As I said before:
Please do not spread misinformation. If you're not sure, ask. If your English is not good, ask someone to help explain. These distinctions matter and it's all very confusing to somebody new.
