Forgive the stupid question that is fast approaching. Ya know how UT2k4 has that little music player...well I never use that anyway...but just how much does playing mp3s in the background like in WMP or what I use, Musicmatch Jukebox REALLY affect your FPS and anything else? My computer is probably at the halfway point between the minimum and preferred system requirements for the game. I know they always say "disable as many background apps as you can"...is that why it's probably best to play an actual audio CD instead?
It certainly will suck up quite a bit of ram up,but the slice on your FPS/smoothness highly depends on the amount of RAM(not really sure on how much CPU it takes)
