I am wondering if any one has upgraded Dell Optiplex 745 USFF CPU from Intel® Pentium® D to Intel® Core™ 2 Duo 1066MHz , and does it make any increase to the performance in the computer .

I have not actually done such an upgrade but looking at the specs I don't see how it could not improve performance. The amount of improvement, however, would depend on the caches your current CPU has and the caches you get in the Core 2 Duo. If you have a low cache CPU now and go to the top of the line cache in the newer CPU, you'll get the best improvement. If you have a top of the line Pentium D and go to the lower cache version of the Core 2, you'll see less improvement.

Of course, that all depends on what you are actually running on the machine and whether or not the CPU creates a bottleneck with whatever other hardware you might be running. If it does create a bottleneck you probably won't notice any improvement.

what is running now is Intel® Pentium® D 800MHz FSB Socket T with Dual Core technology XD, EM64T, 2x2MB L2 cache, EIST, and VT on 950/960 (900 series)
the one i attend to install is ;Intel® Core™ 2 Duo 1066MHz FSB Socket T with Dual Core technology XD, EM64T, 2MB and up to 4MB L2 cache, EIST and VT (E6000 series)
