I have been looking to upgrade my speakers on y new computer for a while now and have come across the 2 that i like, but I am not sure which one to choose.

A. I have the Logitech Z523 2.1 speaker system which has a nice subwoofer and great price

B. I have the Creative Gigaworks T40s which yes are more expensive and 2.0 configuration but im willing to dish out the cash.

My main concern is whether 2.0 or 2.1 configuration is better and which set of speakers is better.
if anyone has any recomendations for diffrent speakers that would be great as well

I mostly play games on this computer but also watch movies and play music.
