if your not going to get a sound card with dolby digital decoding, the speakers i use are altec lansing ada885 (ada890 also available) which i picked up for 180 shipped new. they come with a wireless remote, 5 different settings, and a dolby digital decoder built in if you watch DVDs or for games that have 5.1 surround.
they are good, not as loud as the z560s but definitly worth 180bucks shipped! very loud and the sucessors the ada890 have been billed as the most versatile speaker system available (both the ada885 and ada890 can be converted to either a 5.1 setup or a 2.1 if you dont have enough space, they sit on top and plug in the front speakers and work together!!!), and have the most balanced sound of any computer speaker systems.
worth a look.
"dude your getting a dell", is that kid trying to say he wants to stick his 'dell' in you?
