Dude, you should not have any worries with that PSU. It's sufficient for your needs. They recommend a better PSU because there might be a chance that you have a bad PSU that does not provide its wattage as advertised and ultimately melts down your GPU.
IMO I find those monitors a little to wide for their height and it just looks strange, plus I need some wiggle room in terms of vertical space.. sadly they're the opposite of that.
I don't have a powerful PC either. I only have a Sandy Bridge i3 along with a shitty GT 440, and the impact is actually minimal, others affect the FPS by ~10
I don't know, I have the same controller and it came in a Microsoft box... At least it was labeled that way. And that's exactly the same but doesn't fell bad in any way, I think I may have the box. Need to look around a little.
Dude, he means that they don't support it out of the box. You need a working CPU to flash a newer BIOS on the motherboard and then you can use that new CPU.
Um, there's a significant advantage in running COD4 at 250FPS. That's considered as a sweet spot. Because there's a bug in the engine that supports the game — It allows you to run faster and make higher jumps for glitching, etc. In other words it's an unfair advantage.
I still play COD4 to this day, and I can guide you on this a bit.
1. That PSU seems to be enough. Go for Seasonic.
2. The 750 is a bit better in terms of performance than the 260x.
3. Yes you can on 768p. But don't expect Ultra.
4. I think you can. Not sure but it's likely you will. Assuming you run it on highest settings including AA. But if you turn down those things a bit, then I'm sure you can.
EDIT: You can limit your FPS to 250 or 333 by using the Console.
Press ~ on your keyboard(Under Esc) and the console will open. Type in the command "/com_maxfps xxx" and it will limit your fps to those numbers. "/com_maxfps 250" in your case. Keep in mind the console is disabled by default in the game settings.

And yes, I really need those things I'm currently on an unbranded not-even-80-plus power supply and a GT 440 that goes to 100°C in BF4.
I use Chrome Canary, and yeah it's 64-Bit. And no, it's never broke down on me. Till now that is, because it is sort of a nightly version of Chrome that gets updated almost everyday by Devs trying out new features.
If you're playing games like Borderlands 2 and you play other games or use some programs that utilise the PhysX engine then and only then I would choose the 770 over the 290. Otherwise, there is no reason to.
