Ok so here's the story. I bought Starcraft 2 today, came home and installed it onto my computer. As soon as the game connects to Battle.net my system's performance drops like a rock. Its constantly lagging to the point where the voices are jumbled and the frame is skipping at least once second. So I restarted it and tried again multiple times with the same result. So I unplugged the internet and started to play offline and to my surprise it was running great. Now I have a pretty good computer but I'm not all that great with them. I updated my all my drivers and opened all the Battle.net ports on my router but nothing seems to be working. Here some Direct X Diagnostic screens. Any help or input would be wonderful I'm kinda suspicious of a hardware failure as well.

Did you install the SLI chipset software for your motherboard? My buddies nforce 980 system would work without them (including the network drivers), but I installed it anyway. You might need the proper network driver found in that package.
