I dont think i have space for 5.1, so a decent 2.1 set would suffice, i need one that sounds good, but wont break the bank under £40 preferable, closer to £20 would be nice, i have a xonar DX to go with it for decent sound. Only other thing to mention is that i am replacing a set of rather cheap logitech 2.1 OEM ones, which have lasted me for a while, but now the volume dial makes the right hand speaker cut out at certain volumes.
