For one thing, you can't use your modem when you want to play online, which most peeps playing computer games do, like counter strike or such. I only tried it like 2 months ago i think and i didnt spend enough time to learn it, maybe you can use modem, but I didnt see much performance gain. Maybe if you have 32 ram you might LOLOLOL.
