I'm not absolutely sure on this, but I don't think most music is recorded in surround. So even running it through virtual surround isn't going to make it "surround", so much as just add reverb and crossfeed. I could see movies benefiting from its use, but games would be highly questionable. Most games' audio engineering is kind of garbage, their audio engines that generate sounds from x,y,z coordinates can be very buggy. From a cinematic sense, in a AAA title, maybe you'd see some improvement in immersion? Assuming the virtual surround distortion doesn't distract you. But competitively? There won't be much improvement.
