good call on the keyboard, god damn
also what brand of video card are you running? EVGA? Asus?
I got the overclocked ASUS Strix. Seriously, the thing runs like a charm. Been just throwing on any resource intensive game every once and a while, turning on my temperature monitor, and watching as it gets to 60 C the fans finally turn on, (need to adjust the curve), but after they're going the card stays around 60 maybe at the most breaking 70, though I can't say for sure if I've seen this happen. Also I have yet to overclock on my own.
Runs stuff like Hitman Absolution, Watch Dogs, and Witcher 2 on usually the highest settings with some tweaks and it runs at 60 fps pretty smoothly. Watch Dogs being a poorly optimized piece of stuff though cannot be run on ultra for whatever reason. I do have confidence GTA V, Witcher 3, and whatever AAA's I throw at it will run on at least high while maintaining a reasonable fps.
Then again, if I could afford a second one right now I'd order it today, lol. :) Also I should I note that I don't have an i7 processor, so I'm not running on the best hardware out there, but it does the job beyond my hopes and dreams.
Edit: Saw your edit of your updated list. I got my card for like $350, don't know if they're still out of stock, but whatever retailer is selling it for nearly $400 is charging you a bit too much. Also make sure you get the overclocked version.
