Intel doesn't offer the 2 socket Quad in the Quad Core line. It is however available in the Xeon's (which can be Quads today.)
The fastest road to getting such a machine is over at apple.com in it's Mac Pro model.
Thankyou for reading my post... new to building computers so please take this as a novice asking questions... but this is for work and we have some Money to Drop on this Porject...I produce a 30 min tv show each week and would like to use 2 Quad Core Processors. In the same line as the top line Apples with 16GB Memory...I am thinking of the Quad-Core Intel Xeon ?Clovertown?3.0 GHZ Processors that apple uses. I built the PC I am using now... 2 years ago ... 3.0 pent D dual processor with 2gb of Corsair XMS2 and a Radeon 512mb video card.. I have not seen much info on building a PC with 2 Processors. The only motherboards I can find that hold 2 processors are Server boards. What is the Difference between Server and Desktop Motherboards? What should I be looking for in a Motherboard that has two sockets? I know my PSU will be over 1000W ...looking at the OCZ 1010 SLI ATX12V / EPS12V..OCZ is what I have now in my old computer. With the OS can I use Vista64 or do I have to Use a Server OS? Also torn between getting two EVGA 8800 Ultra's 768MB in SLI or two HP NVIDIA Quadro FX4600's 768MB in SLI..Dose SLI help rendering? I sometimes spend two to three hours on a 15 to 30 sec video render in After Effects with the current setup...the Document for the Asus Server Board I am looking at says I have to use 240 pin FB-DIMM Modules unlike the DDR2 DIMMS in a desktop.it has a Note that says that FB-DIMM Socket has Advanced Memory Buffer (AMB) chip that allows memory to CPU connection at gigabit speed. Is this faster than Desktop Memory? why does it cost less? I am looking at spending 8 to 10,000.00 total on this project and am looking to build the fastest Video Work Station I can build with this amount of money...if you want you can contact me dir at email@example.com..Also please keep in mind .. I would like to build this PC... I could spend the 12 to 14,000.00 and buy an Apple but where is the fun in that... This is for a growing company and will be a Workstation Computer ... not something to edit the family videos on.
