First of all pardon me my English. I was wondering what is SNR means does it matter much about gaming? I have 2012 motherboard and onboard sound card is good enough for day to day task but when it comes to gaming i can barely hear a thing. Searching on google apparently my onboard sound about 90SNR and considered getting Creative sound blasterx AE-5 it's 122SNR and two separated left and right sound crossover. Does DAC amp will do the same to internal sound card in term of gaming?Played a lot of PUBG ,CSGO,Overwatch all the games that takes advantage of having good hearing. I did all the sound guide from changing 7.1, 5.1 stereo to compressed sound every sound guide you can imagine I did it all getting Sound blasterX AE-5 is my last resource.
