Depends on how much power you need. You use a Socket 775 processor for a socket 775 motherboard.
Core 2 Quad @2.66Ghz, $169.99
Pentium Dual-Core @2.93Ghz, $79.99
The more power, the bigger the price.
They are basically formats for which CPU format will fit into what board. For example, any core 2 duo processor from Intel is probably an LGA 775 and will fit into LGA 775 socket motherboard. Any Core i7 processor will fit into any LGA 1366 socket motherboard. The list goes on.
You cannot install an Athlon 64 X2 CPU into an LGA 775 motherboard, as the Athlon 64 X2 uses the Socket AM2 or AM2+ interface, while LGA 775 motherboards are designed for Intel CPUs. To upgrade or change your CPU, you would need a compatible motherboard that supports the Socket AM2 or AM2+ interface for the Athlon 64 X2. Always ensure that you have the correct motherboard and CPU compatibility before proceeding with any installation.
The Intel Core 2 Duo E8500 Dual-Core Processor fits in an motherboard with a socket type of LGA 775. If you are purchasing a motherboard for this type of CPU, make sure you purchase a CPU that clearly indicates that it is for Intel processors with a socket type of LGA 775.
Each motherboard possesses certain socket type, for instance, from Intel LGA 771, LGA 775, Socket 478, 604, Socket M and P, for AMD Socket 754, 939, 940, AM2, AM2+, Socket F and socket S1. Thus, when you are going to buy a motherboard you have to have or buy a CPU with the same type of socket. A CPU with one type of socket will not fit another type of socket!
It is more expensive than a single CPU socket motherboard
The number 755 referes to the number of connections between the processor (CPU) and the socket that the CPU goes into. The number (and configuration) of connections between the CPU and the socket must be the same.
In the motherboard socket.
That refers to the place where the CPU is plugged in.
No, it's not.
No, it's not.
Socket A.
The microprocessor is installed into the CPU socket on the motherboard. A CPU socket can only fit a certain range of microprocessors.
