About System Requirements

I'm currently playing on a GTX 970, and of course have no issues whatsoever in game. I want to use EVGA's step up program to get a 980 instead, the problem is that I would be out of my gfx card for about a week.

I'm getting mixed comments on whether the Intel HD 4600 integrated graphics on my i5 will at least run the game (I will probably just fall back to fate grinding a new class while it's gone). I know I'll have to drop my resolution significantly from 1440 as well as my detail to low, but I'm fine with it providing I can at least play for the week.

Before taking the time to take out of my GFX card, I just wanted to know if anyone has run it successfully, as I've seen some people say it won't even boot the game on Intel HD and minimum requirements seem to suggest an older nvidia/amd card is required. Alternatively I can drive down to MicroCenter (about 2 hours each way) and pick up a temporary gfx card to have to go return later, but I'd prefer not to if possible.

Any help would be appreciated, thanks.
