Tiens, concernant le 64 bits qui a l'air d'en intriguer plus d'un... Je suis tombé sur un post (DUC-section TDM) qui résume assez bien la chose je crois. Au cas où ça vous intéresse et où vous lisiez l'angliche, j'le copie colle direct (sinon passez juste votre chemin...) :

-----------------------------------------------------------------------------------------------
What I was getting at is that I get the feeling that people are spouting off about 64-bit without knowing exactly what it means–or more specifically what it refers to. They just think, “it’s a bigger number, so it has to be better.” The truth is there are many parts to a CPU and I was asking if anyone in the “We had it (or are gunna have it) first” argument actually knew what they were talking about. To clear things up, let me explain.
When talking about bits on a CPU you will normally be referring to:
1) The DATA bits
2) The ADDRESS Bits
3) The Registers
Are they talking about the DATA bits? No. The DATA bits have been 64 for a long time now. Those are the bits that come and go through the CPU. An increase in the DATA bits would improve performance because data could be sent and retrieved at a higher rate. However it comes at a great cost. Each DATA bit requires a physical pin on the CPU and a trace on the mother board. It also requires the supporting chipset and/or memory to have the same number of DATA bits. This gets tricky and expensive so the prevailing wisdom has been to increase bus speeds.
Are they talking about the ADDRESS bits? Yes. The ADDRESS bits tell the memory what bits to send to the DATA bus. Currently most systems can address about 4GB of memory. Increasing the ADDRESS bits to 64 would allow a system to address about 18,000,000,000GB. Will this improve performance? Well, all those that have maxed out their motherboards with 4GB and are getting “out of RAM messages” raise your hand.........I thought so. Not to say that I’m not happy to see chip manufacturers preparing for the future, but to claim some sort of system superiority at this time is nothing but marketing hype. By the time we NEED 64-bit addresses, every new computer will have it.
Are they talking about the Registers? Yes. The registers are the “holding tanks” for the data the CPU is going to work with. By allowing a CPU to hold bigger chunks of data, the CPU can work with larger numbers faster. Will this increase performance? Yes and no. If you’re doing some complex CGI rendering, yes. If you’re doing complex scientific calculations to crack the mysteries of the universe, yes. If you’re recording or mixing 24-bit audio, no. Most everything we do in audio will see very little (if any) performance advantage with 64-bit registers.
So, in short, this whole 64-bit thing is irrelevant to us. It’s important for those who seem to have the need for bigger things. For those who will spend the extra $1000's to get the monitors that will go down to 10Hz and put them in their 15'x20' project studio. (Do the math).
