Do additional monitors drop performance in game?

post #1 of 4
Thread Starter 
So I currently have 4 USB monitors I use for work and my main Samsung display connected to the video card. I was about to slap another GTX 780 in the system to run SLI for games, and I was wondering if I would lose performance / drop fps if I were to ditch the USB monitors and run the additional displays on both my graphics cards? I would still be only using the main display for gaming but I was worried the additional monitors would use up some of the 3GB of VRAM to display steam / mp3 player / web browser / ect, and I hear that BF4 uses well over 2GB.

Would it be worth it to snag maybe an additional cheap 1 slot PCIE video card such as this http://www.amazon.com/EVGA-GeForce-2048MB-Graphics-02G-P3-2639-KR/dp/B008Y8PON8/ref=sr_1_3?s=electronics&ie=UTF8&qid=1385797781&sr=1-3&keywords=evga+geforce ? Or might I be worrying for nothing?

You'll be fine, the difference, if any, will not be noticeable. Quite simple really. if nothing is rendering to those displays, the GPU isn't doing much work to display the content. And indeed on Windows the DWM does not do any compositing while a full screen application like a game is running.
