Originally, I was going to go 4K for this build, but I had 30+ people talk me down on Overclock.net and other forums. So, instead I decided to go to 1440p. With Asus coming out with the new ROG Swift PG278Q, which is a 1440p monitor with Nvidia's new G-SYNC in it. I got a big budget of $4000, and if I don't have to spend it all to reach what I want in 4K, I don't want to. I'd rather have some money left over when I'm done so I can continue saving for a car. If I have to use this budget, thats totally fine by me.

Originally, I was planning on buying 2 EVGA GeForce GTX 780 Ti Superclocked w/ ACX, and put them in SLI. Now I'm wondering if SLI is going to be overkill for 1440p, especially with 780 Ti? I may be wrong, which doesn't matter to me if I have to buy the cards, I was going to anyway. I'm just looking at ways to save money here. I wanted to Max out games like Battlefield 4, Skyrim on 1440p. Help?

Hi,
The OPTIMAL configuration is to get a single GTX780Ti, and the new G-Sync, 2560x1440 monitor.

With G-Sync you no longer have to worry about reaching a particular target such as maintaining above 60FPS to keep VSYNC ON.

For really demanding games like Crysis 3 it may make more sense to run at 1920x1080 even with a GTX780Ti. Shooters often don't look much better above this resolution but can take a big hit. Top-down "god" games on the other hand often look far better at 2560x1440 because of the small HUD/Text elements.

RESOLUTION is just one aspect of the ultimate game experience. Frame rate, quality settings, latency, PhysX etc are all factors as well. The dumbest thing I think I've seen is someone running below 30FPS at 4K with a...

if you have SLI 780Tis you won't have to worry about upgrading your system for a decently long time. If you only wanted to max out those games, sure, it's overkill @ 1440p, but if you decide to play more graphically demanding games you'll be glad that you invested in the SLI 780Tis.

RESOLUTION is just one aspect of the ultimate game experience. Frame rate, quality settings, latency, PhysX etc are all factors as well. The dumbest thing I think I've seen is someone running below 30FPS at 4K with a 2xTitan setup.

Tweaking rule-of-thumb:
If you can maintain 2560x1440 at max settings and still maintain your FPS goal (i.e. 50FPS average + with G-Sync working) then stay there, otherwise drop to 1920x1080 which looks nearly as good or identical.

(For non-G-Sync, I do the same as above but tweak to maintain 60FPS at least 90% of the time and often use Adaptive V-Sync.)

4K:
I don't recommend this. For one thing, G-Sync has no 4K upcoming monitors yet, and G-Sync really is the ultimate solution for smooth gaming. Also 4K looks basically IDENTICAL to 2560x1440 in gaming but you get HALF the frame rate. If you had a 4K monitor, I'd still be telling you to play at a lower resolution.

Lightboost:
Read about this, but basically I believe you'd want to be running 100FPS+ to have this feature on.

Summary:
*Get a single GTX780Ti, the Asus G-Sync 1440p monitor, then tweak the settings to get 50FPS or better average. You can always add a second GTX780Ti if you need to, but I doubt you will.

^ while true that you do not need 100+ FPS to enjoy a G-sync monitor, that is not to say it isn't better at 100+ FPS. So I guess the question is whether or not the added cost is worth it to him.

I haven't purchased a G-sync monitor yet, though the above one is top on my list of choices, but I can tell you that 60 FPS is not good enough for me due to simulator sickness. I'm curious to know if G-sync at 60 FPS would be good enough for me. I doubt it will, but until I try one, I won't know for sure.

I doubt that G-sync is the future for a couple reasons:
1. It is only limited to Nvidia graphic cards
2. AMD has free sync which can be used by nvidia and is already the display port 1.3 standard
3. A lot of people will not pay a couple hundred dollars for G-sync

It doesn't matter if G-sync is the future or Adaptive-Sync. They do the same job, and do not require any special support by the dev's. That means if you buy a G-sync monitor, it will remain effective for years, regardless of what system sells the most in the end. If you want that type of tech now, G-sync is your only choice.
