Naw, it's easy to get 1366 socket parts (motherboards, liquid coolers, etc.)

     You can't go wrong with the core i7 hex. :)     32GB will probably be enough, but to allow for future expansion, use large denomination RAM sticks, filling only half of the DIMM slots, so that you can add another 32GB if you ever choose to do so.  If you use all of the DIMM slots to reach 32GB, then you'll have to toss it if you decide to upgrade to 64GB.   The 4GB video card should give you excellent Vue preview quality. 

     If you have any other computers sitting about, remember that Infinite comes with licensing for five Render Cows, so you could run your newly upgraded machine as the master (and run a Render Cow on it) and run Render Cows on four other machines.  Just install Render Cow on the slave machines and jack them all into the same router.  It's a great way to get some use out of machines you no longer use, if they have enough memory for the current render project.

     To install a Render Cow on a slave, run the Vue Infinite installer, but choose install network renderer instead of install Vue Infinite, and in the next prompt, choose install Render Cow - not render node!  If you have several extra computers, you may install Render Cow on as many computers as you like, but you can only engage five at a time.
