I assume you need a new pcie sound card because you upgraded your motherboard which no longer has PCI slots?
If that is correct, can you tell us what motherboard you got? There is a good chance your on board audio on your new motherboard is on par with these sound cards.
If not, I would go for the asus stx 2 card. All you need are some 3.5mm to RCA adapters and you will be good to go.
