Is the GTX 680 4GB good enough for a 120hz screen?

[brunokill]

Ideally I would want my games to be over 100fps to get the most out of my screen. Would this card achieve this on ultra settings?

And one more question...
Will this run good with an i5-3570k and an ASUS® SABERTOOTH Z77? Is this motherboard future proof?

In most modern games; no. The GTX 680 2Gb scores about 60 fps on average in 1920x1080. The 4Gb model performs at a similar level if not slightly worse, giving no benefits from the extra memory at that resolution.

Generally you only want more than 2Gb RAM when running resolutions that are above 1920x1200. If you want more than 100 fps with all settings maxed then you should get 2 x 680 in SLI or 2x 7970 in Crossfire, which might pose additional problems however...

What kind of problems?

A 680 4GB is a total waste of money just get a 2GB card.... exact same performance.

Anyways, getting 100fps+ will depend on the game and the settings you are willing to use. A single 680 will not max many new games at 1080p at 100fps+, but it would do fine with some settings turned down and of course it will handle less demanding games fine. Also be aware that you'll need to overclock your CPU heavily for some games to get above the 100fps mark.

No such thing as future proof in computing, but a 3570k + sabertooth z77 is a fine build.

What cpu do you recommend for gaming with 2 680's in SLI 100 FPS?

He means microstuttering, which some people definitely notice. It occurs when using two cards in SLI/Crossfire. (3 cards practically eliminates it though). Using 2 cards also uses more power/space and uses more power.

Edit: Your i5-3570k will be more than enough to handle gaming at 100fps with 2 gtx 680's in sli. The graphics cards will still bottleneck that cpu at any resolution while gaming.

Well for one you need more power draw from your PSU and an SLI/Xfire compatible motherboard, as well as a powerful enough CPU and around 8 Gb of 1600 MHz DDR3 RAM so they won't throttle your performance. It is well known that dual-card setups also introduce something called microstuttering which is more apparent to select individuals than others and may require careful setting and/or fps optimizations on your part.

Should note that even if you can't see it or will be able to effectively minimize it, it will still always plague setups that use several GPUs.

Absolutely it is, although you only need the 2gb version. You can tweak video settings to get close to or to 120hz in many many games. 120hz is amazing. The 680 is the most powerful card available atm, or the 7970. Don't go SLI/Xfire.
