1.This new one is 64-bit? or 32-bit? 2. The FSB is 800MHz now. But the memory is still 667MHz and somebody said you can't get performance improvement even use a 800MHz memory stick. Why? The lower speed of memory will not be bottleneck of the CPU? 3. Is the memory 64-bit or 32-bit? I mean how many data will CPU transfer in/out of memory once a time, 64-bit or 32-bit? I'm a newer. I hope I have expressed my questions well. If not, just point out please.
