Since I hijacked this thread, I figured I'd post an update/resolution as a warning to others.
So I ordered an EVGA GeForce GTX 1060 SC, specifically this one:
https://www.amazon.com/gp/product/B01IPVSLTC/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1Amazon Prime delivered it two days later, and I excitedly opened up the box, ignored the warnings about not being able to return opened items, and read the installation instructions. It seemed simple enough. I opened up my computer case and got my tools.
The first problem reared it's ugly head in the test fitting. The graphics card's backplate interfered with the back of the case. Ok, no problem. I studied the placement of the retaining screws, took the backplate off, popped the dummy plates off the back of the computer case, and it fit in the slot. Problem solved. I thought I was on my way.
Second problem: the new card came with a power adapter cord, but that assumes that the host motherboard actually has a place to plug it into. Mine doesn't. I guess the onboard Nvidia card was fat and happy being fed power through the motherboard. Ok, well, let me just hook it all up and see what happens.
Third problem: the monitor plug didn't fit into any of the receptacles on the graphics card. It was just too old. End result: not only would I need to upgrade my power unit (I guess, not really sure on that since I never got that far in the installation process to test the card), but also my monitor. Oh, and probably my motherboard as well. Ok, this was going in the entirely wrong direction. This was supposed to be a way to save me from having to layout money on a new computer, and instead it was developing into a "buy everything but a joystick" problem.
Looking at it from an accounting standpoint, I'd be laying out about $1k to play a $15 a month game. Alternatively, I could just eat the $260, save myself $15 a month, and go outside to play instead of flying cartoon airplanes.
Looks like I'll be spending my tax refund next March on a new system.
Anybody want a new GTX 1060 SC? PM me. Might as well get what I can out of it.
