You don't need a sound card and 2tb is way too much. You could get a 1tb for half.The integrated sound is better than that dedicated card could put out.
I want a LOT of storage space so I can install a LOT of steam games, and as for the sound card, read the reviews.
forget offI have valve complete pack and a TON of other stuff, steam folder is 99GBAlso, unless your speakers are ~$500 a pair, you don't need anything other than integrated sound
