G73 Game Streaming and Drivers question

Hey everyone.

I got 2 quick questions.

1. I tried streaming on twitch tv and as soon as I turned on the streaming software (Xsplit) it kinda laged everything up, made it slow. Does anyone use the software or in general stream from G73?

2. I've formatted recently and was not able to find all the right Drivers. The once I found on this forum were linked to Rogue forum and they are all outdated and are not downloadable. Does anyone know a good source where to get all the drivers?

And final question I've updated ram, basically had 6GB(3x2GB) before and now have 12GB(2x2GB and 2x4BG) Along with that I've upgraded to SSD and formatted. Now it seems the computer is not functioning properly(for example it cant handle 2 World of Warcraft clients running at the same time) it lags up the system.
My question is, could it be caused by not having all the right drivers, or ram problem(its all 1333) or SSD?

 

Here's what was the main source for drivers, some links should still be working: G73/74/53 Series Driver and Application Reference

Here's a small list of the drivers i use, most are still up to date: http://forum.notebookreview.com/asu...40272-asus-g73jh-driver-disc.html#post8334226
