Well, since you have almost all the parts you need, why not just install Windows on the machine you already have? Your only issue with that plan is running 2x GTX 770s, which you'll need an additional PSU for. Would cost a lot less and achieve the same result.
 
I would:

- buy a Windows 10 license and Boot Camp
- sell the 2 GTX770s
- buy http://www.macvidcards.com/store/p49/Nvidia_GTX_980_Ti_6_GB.html

or

- http://www.macvidcards.com/store/p44/Nvidia_GTX_Titan_X_12_GB_(Maxwell).html

and use the rest of your budget for Solid State storage, backups, new monitor, etc.


Thanks guys or all our help I am a VfX artist that is using octane render and i need 2 graphic cards to run octane. Right now in my mac i have GTX770 and 5770 GTX is ruining on separate power and i dont have space to put another GTX i alos upgraded this mac with SSD and HD. I would like to move from mac to PC but would love to salvage as much as i can.

Thanks again

There is power in Mac's PSU for second GPU but you'll have to harness it yourself (we're talking about 980W PSU here) :)

Also, assuming you have W3520 CPU, you cannot use it in dual Xeon configuration.

Idea to save money

Say for instance I decide to put a triple slot height graphics card in my 2009 Mac Pro, the second 16x slot would be blocked. Could I use a 3m PCI-E extension cable to make use of the second 16x slot? I appreciate any PCI-E device wouldn't have a 'secure slot' but it could be secured in the case by other means.

Basically right now i have GTX 770 4gb in my mac and 5770. GTX is powered by external 500w power supply my idea is to get 3m PCIe x16 riser cable and connect another 770 that would be attache outside via another power supply. I see people doing this in PC and it works i wonder i it will work with mac

Here is the cable i will use

Unless you spend a lot on PCIe riser cables, they can cause all sorts of issues. Why not try and sell the 770s and get something like an R9 Nano, or 2x RX 480s. No external PSU required.
 
I don't use Octane, so I'm asking: Why do you need 2 video cards? One Titan or 980Ti that I linked would run circles around the dual GPU setup you seem determined to pursue.

Also, OP are you aware that you can run Boot Camp on your Mac? Much simpler than trying to transplant components.

Octane will only work best with 2 gpus And yes i know i can run boot comp i am just frustrating when it comes to upgrading mac
