Im a pretty big sound nut -
I would recommend the Z-5500 from logitech
It all depend on what you want -
Deep bass ? the 5300 or 5500 would be great
Good Highs? The X-530 Is good (logitech)
the 5500 is an all around god system (with an online price of about 250 - 300)
Or you can go cheaper - the x530 is only about 70 - 100 depending on where you go - Low wattage - But decent highs and lows (mids are ALITTLE lacking) But still a good deal for the price . . .
Or you could go the reciever route . . . Thats what i did after going through about 4 speaker systems i didnt like (Well i liked them - Just didnt get the big sound i was looking for) - I decided to go with a reciever
I run my sound into a sony 900 watt reciever piped out to 6 satelites and a 12 inch sub -
Sounds awesome
Another big part of your sound will be your sound card - I would recommend the audigy 2 or 4 - I have the 2 zs - sounds great
It all depends on what you want - I like big speakers and big sound (so i paid a pretty penny)
- I also watch DVD's on my computer
Get what you can afford : )
My only complaint about computer speaker systems in general is their wattage - You cant get big wattage without spending alot of money - So I got sick of it and decided a reciever/home theater system was more versatile -
I like being able to shake the walls (literally)
Ive spent about 500$ on my current sound system . . . I plan on spending more on a better de/encoder - and a better sub (my current is only 125 watt)
