Sadly, altec lansing isn't making pc speakers right now, just personal bluetooth speakers.  I have two sets of theirs and both are great.  If you care about music, make sure you get one rated 40 watts and a 5.25" woofer or better for your 2.1 system.  the 2.1 systems with a 4" woofer are just too weak for music.  I just shopped and bought a $55 set from best buy - Insignia, their house brand, after trying the $30 logitech system and then sending it back.
If you only want to play games with no music listening whatsoever, I would get a pair of $20 class pc speakers.
