I am running a Phenom II 970 Black Edition on a GA-870A motherboard. The sound chip is giving me problems so I want to add an actual sound card to it. I'm looking at the Sound Blaster SBX AE-5. Creative only says minimum requirements are an Intel i3 or AMD equvilent. I even asked them in annemail and they just repeated that statement. If I pay $150 for this sound card, am I wasting my money on it withouy upgrading my system further?
