Ordered a GeForce 1050 ti - should get here Thursday so we'll try again then. I'd been wanting to get a new card anyway - my computer keeps locking up when the browser hits video content, and I've been suspecting it's due to an underpowered card.
That being said, I'm not very happy with the game so far. I had to hunt all over to find a physical copy (ended up having to go to Target), 'cuz I wanted the usual cool map/tech tree inserts and didn't want to wait for one to be snail-mailed, then when I open the box it was essentially just a CD. Then I couldn't play it - the release doesn't feel well executed. I hope this isn't an indicator on the state of Firaxis' corporate health....
