Hi, I just came back from the PC world and can not wait to share one little tip with you.
As the original author said, sound tends to be overlooked by PC makers with the development of technology in recent years. And high-quality audio is nearly always the first thing to be sacrificed when a company puts together a budget desktop PC.
So here I want to draw your attention to the Audio setup. It is said that the tiniest of tweaks can make a huge difference to your home audio setup -- especially if you have surround sound. Whether this tiniest tweaking can make you achieve the sweet spot where Beethoven is divine and Bioshock can almost literally blow you away is waiting for you to give it a shot.
Here is a link of the detailed info:
