i know there's a sticky on this board, but it's loaded with replies. i just put in an ASUS A7N8X-E Deluxe, and an XP2500. i already have an older Creative Labs Sound Blaster Live 5.1 . also i already have an addin card LAN. should i use the SB Live or the built in sound? will using the built in sound take away at my performance or does the built in APU take all the load off of the CPU. same with the LAN as well. i'm not too familiar with the unmentioned guidlines this forum has so sorry if i crossed over anything. thanks in advance.
