What Type Of System Will I Need To Play Games At Max Settings With A 2560 x 1440 Monitor?

Solution
I have a 2560x1440 monitor.

I play most games at 1920x1080. Why? I'll give an example. In SKYRIM, the game looks IDENTICAL at both resolutions. There is a tiny, tiny but of fuzziness on the text at the lower resolution that you'd never notice while playing.

The frame rate difference however is about 30% (for similar anti-aliasing).

It's also interesting to note that even if you are capped at 60FPS, a system capable of 100FPS will run slightly better than at 70FPS (again, both capped to 60FPS). It's a little technical why that is though.

Games I DO play at 2560x1440:
1) Diablo 3 (not that I really play it)
2) SC2
3) Torchlight

Basically games similar to above where you get small HUD and TEXT where the 2560x1440 resolution really...

2) SC2
3) Torchlight

Basically games similar to above where you get small HUD and TEXT where the 2560x1440 resolution really does make a big difference in sharpness. All these games also run at full quality 60FPS so no loss there.

There are only a few games I even need to tweak. I have zero interest in upgrading. I have an overclocked GTX680.

Recommended specs:
1) i5-4670K (OC to 4.1 or 4.2GHz)
2) 8GB DDR3 1866MHz G. Skill
3) Z87 Motherboard (love the new Asus Hero VI for $200. SupremeFX audio, great reviews)
4) GTX770 OC, or GTX780
770-> Asus GTX770 OC
780-> EVGA GTX780 w/ACX (the $650 model)

5) Windows 8 64-bit OEM
6) Start8 from Stardock ($5)
7) CPU cooler (PWM fan on air, or liquid)
8) Case
9) 120GB or 250GB Samsung 840 EVO SSD
10) 2TB HDD for storage/games
etc..
