2 GTX 460 in SLI

now the detailed Problem:

I set up a scene for LoL ingame (windows capture, inner window, mouse cursor enabled)
If i let OBS just run without streaming, im ingame with 60 fps. Right in the moment when i push the "start steaming" button, my fps drops down to 30-50 fps. (as u can see in the log, i stopped streaming for some seconds, fps went back to stable 60 until i started again, they dropped.

Anyone an idea, how to fix this? Do i need to upgrade to 8 GB of RAM?

PS: Even if i dont start streaming but hit the "preview steam" button, theres also this problem!

Here's a list of things that you could do which should help with performance in your particular case.
-Enable Aero since you're using windows capture.
-Use the 64bit version of OBS
-Lower the stream fps to 30
-Make sure to pause your stream from your browser.

You, sir, are a genius.

i dont know what of these things did it but now its constant 60 fps!

64Bit... i downloaded the installer, it automatically installed the x86 to C:\Program files ( i was angry about this, cause i dont want anything on my C: (SSD). so i deinstalled it, downloaded the binary and unzipped it, so its not installed anymore but works.
