Hello!

Here is two CPUs:

Core 2 Duo E4700 (2.6GHz, 800 FSB, L2: 2MB)
Core 2 Duo E6700 (2.66GHz,1066 FSB, L2: 4MB)

The biggest differences about the processors: the FSB. Let's fancy
another two processors:

A: Core 2 Duo (2.6GHz, 800 FSB, L2: 2MB)
B: Core 2 Duo (2.6GHz, 1066 FSB, L2: 2MB)

Can I feel different performance if I don't change anithing in the
computer except the CPUs (A -> B)? Of course, the motherboard support
both type of CPU.

Does FSB speed matter?

Thank You!
 
FSB speed does matter, but you will need faster memory to take advantage of the higher bus speed. L2 cache size also matters. There could also be other differences between processor cores, although I believe all Core 2 chips operate essentially the same.
 
question is do you need the extra speed and are you willing to pay extra to
upgrade the ram

Thanks Mike!

The RAM in the machine is fast as possible but the CPU is not. I want
to replace the Pentium D but I didn't know, witch one is the better
choice.

Darklight,
I've got 4 GB RAM but the CPU is "not the best".
