I will provide details about my current configuration if that helps the community in answering my question:
Motherboard: Asus P9X79 LE
Processor: Intel X79 Intel i7-3820
Memory: 4x4GB 1600MHZ
Power supply: Xtremegear 800W
Graphics: EVGA GTX 660 Ti 2GB
Monitor: 2 x Samsung 23" S23A350H (Both monitors are set to 1980 x 1080.)

I am looking to upgrade my graphics card and purchase either the GTX 760 2GB or 4GB.

I play League of Legends on max settings and I have no problems. I easily achieve 60 FSP if I select V-Sync and without that option, I obtain 110+ FPS.

The issue arises when I decided to stream on Twitch.tv, using Open Broadcast Software. That's when my FPS drops considerably into the 30's. The game becomes a bit choppy.

I would still like to play LOL on max settings (as long as I can obtain 60 FPS on V-Sync), while having the ability to stream at least 720 as well.

I was wondering whether the 4GB, the extra 2GB of VRAM, would alleviate this problem. However, I've read that for the 760, 4GB is a waste of money since it won't be able to fully utilize all the VRAM.

I do have a budget of about $400-$500, so probably looking at GTX 760 or GTX 770. I would like to note that I am ONLY looking to purchase a nVidia card (not AMD). I would prefer a single upgrade card over buying another GTX 660Ti and doing an SLI. However, if a single card within my budget does not suffice, but SLI would alleviate the problem, then I will do that.

I would say 4GB if you are expanding the resolution over both.

No with just two displays a 4gig card is not going to solve your problem. That has nothing at all to do with the memory. Truthfully I do not even know if upgrading the GPU will even solve the problem you are having. You may not be able to do both at the same time.

However if you have the PSU and a second x16 PCI-E slot on the motherboard you might be able to do it by using the new GTX 760 for your game and keep the GTX 660ti and plug the second monitor into it and stream from that card. That would let the GTX 760 run just the game.

even with 3 screen gaming, 2 or 4 GB has no noticeable effect

What is your CPU usage when doing both these things ? You bought an X79 system so I have to imagine something you were doing was CPU and RAM intensive.

Twin 760s would cost ya $520

My power supply is 800W so I should have enough power for another graphics card.
In addition, I do have an extra slot on my motherboard for a graphics card.

Not sure if you are able to answer this question, but what's the difference between what you are proposing, GTX 660 Ti for secondary monitor and GTX 760 for game, and getting two GTX 660 Ti to make an SLI?
What are the advantages and disadvantages to both?

Thanks for the link and the information.

I haven't checked out the CPU usage while doing both.
I just purchased an X79 system just for gaming. Maybe that was an overkill.
