planning on getting a new gaming rig with 275GTX, E8400 and a 23" dell monitor. Was considering going with sound blaster audigy SE, but wanted to know if its really all that better than onboard sound. the total cost goes up by about £70 with soundblaster audigy SE because I also have to buy the next highest PSU if I go for this card. so is the soundblaster option worth getting over the onboard sound?
