I have never tried any of the consumer cards like Asus. One thing to consider is that pro level cards have transformer coupled outputs which would help greatly in isolating your dac from your computer. There are probably some consumer cards with this as well though. Pro cards are expensive though. I got mine on Ebay for less than half the retail price and there are usually a bunch on there. Gearslutz.com often has used cards on their for sale/trade page.
