Yes
There is none. The Pentium D is based upon an older architecture and is slower, at any speed, than any Core 2 Duo processor.
39% of 945 = 39% * 945 = 0.39 * 945 = 368.55
The list of supported processors by 945 chipset is rather long. Please refer to related links to find out full list.

The 865G chipset offers solid performance through a variety of exciting features, including dual-channel DDR 400 main memory, an 800 MHz system bus, and an integrated graphics controller with Intel® Extreme Graphics 2 technology.
1 and 945
The CPU can be upgraded only if your motherboard/chipset and BIOS support it. Socket 478 motherboards cannot support a Dual-Core, as they use a different socket. If you have an LGA775 motherboard, it may work, but chipsets before 945 are not officially supported and may fail to function properly.
945-666 = 279
945
840 and 945 have a GCF of 105. 945 and 1050 have a GCF of 105.
LCM(3, 27, 35) = 945
578 + 945 = 1523
Your question is very vague. The ASRock 945GCM only supports Socket 775 processors. So obviously the only comparison is that one with a Socket 775 processor installed will do something, and the other will not.
