There will be, when the Xeon range of Intel CPUs move to i7 (Intel codename is "Gainestown"). Intel has not announced if there will be a consumer level i7 dual CPU motherboard as yet, and with 4-8 cores planned for i7 CPUs they probably will not. http://www.electronista.com/articles/08/11/13/xeon.i7.in.early.2009/
Yes there are multiple controllers on all motherboards.
AMD Athlon XP 3200+ 2.2GHz
CPU sockets (or CPU slots) in which one or more microprocessors may be installed
Yes, workstations and servers have 2 slot motherboards.
I take it you mean CPU. CPU Overclocking is typically done threw your motherboards BIOS, which can be accessed during the 1st stages of your computers start up.
CPUs are not normally soldered to motherboards. They plug into a socket that's soldered to the board.
Some motherboards come with a CPU installed, but it is not, technically, part of the motherboard itself, but part of a substructure known as a chipset.
Many/most motherboards have a separate power connector for the CPU. Check your motherboard's installation instructions to locate the CPU power connector. Then connect the matching power supply cable to the CPU power connector on the motherboard.
One of the best is the Intel D865GVHZ ATX Motherboard w/Pentium 4 2.4GHz CPU.
Most motherboards only support a specific subset of CPU's. If you change your CPU you MAY need to replace the motherboard... but if you do that it will include the appropriate BIOS. You may also need to re-install the Operating System.
Not really, if you have a cpu with 1 core and 3ghz vs a multi core with 2.6ghz, the multi core is much better, it can handle more stuff and do it quicker, more cache also helps determine performance.
