just got a nvidia geforce 5500 FX. i know its old but its better than my stock card and it was only like 50 bucks but after installing and updating for vista (ugggg) when i play World of Warcraft my sound crackles bad. it only does it while wow is open. when i close it everything is fine. so while wow is up vent,ts, wmp are all crackly and stuff. didn't start till i intalled the card....which is good but still get some low fps and large inc mem ..
