Hi, I have this following build:

2600k
gtx670
8gb ram
2x 24' LED monitors

I just recently got my second monitor, and part of the idea (besides productivity when doing work) of getting the second monitor was that I could watch streams/videos as I play videogames.

However, while i usually get around 100 fps on games (IE: WoW), I now seem to getting a huge fps loss when playing games and having a stream on full screen on my other screen. It seems weird because depending on the stream I may lose more fps than I do with others. Is there any reasons for this/solutions or could someone explain to me how to increase the perfomance? I didn't think it would cause such a perfomance issue (I've droipped as low as 15fps while doing this)

Regardless of how much VRAM you have or how many cards you have, if you double the number of monitors the GPU has to output to, you can never have as many fps as with the same card or cards and one monitor. If you add a monitor, the GPU has to divide it's attention and resources. It's like watching two kids instead of one. Yeah, it's a lot like that. Also, don't be trolling for points. The OP will choose a solution when and if they decide they have received an answer worthy of picking a solution.

Ok, first of all, how are you going to watch streams as you play games. Isn't that kind of impossible to do both at the same time or do you have separation abilities for right and left brain halves? Heh. Just kidding. Of course you're going to lose frames per second. Your GPU is having to split it's resources to output to two monitors.

There are games that you can run on Window mode.

I would say Upgrade you GPU to increase it's FPS while running on two screens.
