Can Bing's Banelings best Farmville's Ghosts? Tonight, Microsoft and Zynga are going to settle their differences in StarCraft 2. The tech competitors face each other in the final of the After Hours Gaming League , a for-charity tournament between top tech companies in Silicon Valley. Starting at 6 PM PST, tonight's final is the culmination of a month-some of round robin action between Yelp, Amazon, and others.

StarCraft 2's self-professed "funsmith" Day[9] will be doing the commentary, streamed here and embedded after the jump. To the winner: $5000 for the charity of their choice and immeasurable bragging rights.

I'm running out the door now to attend the tournament. For on-site updates, follow me at @elahti as I make the trip from PC Gamer to Facebook HQ, where the finals are being hosted.
