Would really appreciate it if anyone could tell me what Optical Drive and Sound Card I should get for my mainly gaming pc build (http://pcpartpicker.com/p/4RMYD3) since I don't know anything about electronics and what makes an Optical Drive or a Sound Card 'good'. Mainly gonna use the Optical Drive to watch Blu-Rays and maybe listen to some CDs from time to time. Wanna spend about 100$ total but willing to go a bit above that if you deem it necessary. Any help is greatly appreciated!
