I am running an EP45t-USB3P (GIGABYTE board) with a 9650 processor. Does anyone know where I could get a 9850 processor?
I just searched for what you gave here and it came up with AMD. Looks like the Intel Q9850 doesn't exist
Here is Intel's product page for all the "Yorkfield" Quads: http://ark.intel.com/ProductCollection.aspx?codeName=26553&wapkw=(yorkfield) And no, the "9860" isn't on there.
Highest you can go to on that board (and that Intel produce) is a Intel Core™ 2 Quad Extreme QX9770. Available here: It would also be in your interest to read your CPU support list for your motherboard, which is here.
I'm somewhat surprised you missed the fact you were asking about a processor that doesn't exist (for your chipset) then....
