Please Help/Speakers 4 The Best Sound

[A_and_P]

Computer is custom built.

Pentium D850MV Mother Board 2 GIG Processor 1 Gig of RD Ram, Video Card G Force 4 TI 4600 128 Meg, Sound Card, Audigy 2 ZS will support 2.1 thru 7.1 speaker system.

I have been looking at:  

Bose 2.1 Only one they make.

Klipsch 5.1 Only one they make

Creative Labs/Inspire 750/7.1 System

If you have any recomendations or suggestions I would appreciate it. Or input on other brands of speakers.

Thanks
