I'm building a pc and i want to have at least some sort of dvd/blu ray player. I have few options and i can't decide if i shpuld go for ASUS BLU-RAY 16X SATA RETAIL BW-16D1HT/BLK/G/AS or ASUS BLU-RAY COMBO 12X SATA BULK BC-12D2HT/BLK/B/AS? The price difference in my country is about 40$. I have few blu-ray cds witch i would like to watch so i would like to know if 12x will be enough for me or i should go for 16x? Is it wirthy 40$?
