Definetly replace these with Klipsch speakers.Speakers - Altec Lansing ATP3 ($63.95)
I would spend less on processor and motherboard. And more on components you're going to be directly interacting with (i.e. speakers).
You could replace this ->
Motherboard - ASUS P48GX Deluxe ($225.95)
Processor - Intel P4 3.06GHz ($699.95)
Audio - CL SB Audigy2 ($126.95)
Total: 1052.85
with this ->
Motherboard - Abit NF7-S ($126)
Processor - AMD Athlon XP 2600+ 333MHz DDR FSB ($260)
Heatsink - Thermalright SLK-800 Heatsink $38
Fan for Heatsink - Panasonic Panaflo 80mm fan $8
Audio - nVidia APU, nearly as good as audigy2 $0
Total: $432
and never notice the difference once you start running your apps (some exceptions) and games.
