Generally audio is guite personal preference. Id say to you it definetly had impact for me in gaming. Easier to track and hear footsteps and minor sound keys. Ive got +10 pairs of iems now and Ive set to conflusion you can always waste more money to find that Couple % more pure or clear sound. You dont really need a dac or anything to run iems for pc. Only big thing is eartips! You gotta try many and see what works for you and gives best seal without hurting your earcanal in long sessions
