. And i dont think you need a Sound Blaster Audigy 2, its way too expensive and its not like has that much of a noticable diffrence than a SB Live! I would just stick to the SB Live! and save some money so you can speend it on other stuff that actually will increase the proformance like RAM or a better processor. And you dont need to buy a $100 cheiftec case, i would just get a cheap case and put some fans it it (save money).
