Thanks for the quick response. I have not tried to enable VSync, I'll try that now =P. As for the cards, would buying another GTX 670 FTW 2GB and rigging my system with SLI be more efficient then one MSI GTX 780 Gaming 6GB? How much does the 6GB offer in comparison to the 2GB (4GB if SLI)? Also, I mentioned Watch Dogs, which seems to be nVidia friendly, but I will be playing a plethora of other games.
Thanks 😀
Be sure to use Adaptive VSync; regular VSync is obsolete on Nvidia cards.
SLI is a great option, and your cheapest, most cost-effective upgrade path. On that chart, you'll be right at the level of a GTX 690, which is essentially two GTX 670s on one card. Just make sure you have at least a 800 watt power supply and that your motherboard supports SLI.
Here's what that review says about the 6GB card: "Compared to the reference design GTX 780 with 3 GB, the MSI 6 GB Gaming is 12% -13% faster, which can be attributed to the overclock only since our game tests conclusively show that there is no significant improvement due to the extra video RAM. The only test where we can see a difference between 3 GB and 6 GB is with Watch_Dogs at 4K (Ultra HD) resolution."

To really see the impact of 2GB of VRAM versus 3GB, go to the linked page where I got that chart. There you can see different resolutions. Compare the 2GB GTX 690 to the 3GB 7990. You can see at lower, less VRAM intensive resolutions, the GTX 690 does consistently better. As you move up in resolution, the 7990 takes over as a result of its VRAM capabilities. The big points are: 1) The GTX 690 isn't seriously hampered by having "only" 2GB of VRAM (per GPU), as it maintains its superiority throughout. 2) The impact is mostly seen in multiple monitors and 4K resolutions. Also check out the Watch Dogs page to see the only real VRAM intensive situation where the GTX 690 has a large drop-off, but only again at high resolutions.
