Well, maybe I´ve expressed this in a strange way...

I wanted to say that there are two reasons that influence my decision of buying wich kind of processor:
1. The FSX and
2. The compatibility to Maya
Because I will need a strong single-core processor for the FSX, I would like to buy a single-core. But I won´t pay a lot of money for a new processor if I won´t have some more avantages from it (meaning: I´m not going to buy a processor just for the FSX). I also would like to know if Maya is possible to support a dual-core and a single-core processor.

I hope I´ve expressed myself now more clearly :--)
