Quick question on this. Did you notice any framerate loss when gaming with DDL/DTS enabled? As for EAX, I have found it doesn't make enough difference to me in games and DDL/DTS pretty much makes up for it. I just bought this card as I have never been fully satisfied with this X-FI Prelude. I am only using Z680's, but since they can handle DDL/DTS this sounds like a sure winner for me, especially since I found it for $150 for an open box at NCIX. Also, even if it does take a hit on the CPU with enough draw to effect framerates, in your opinion, would a Quad core take that hit easier than a dual core?
PS: Killer review. Wish I read it before I bought this X-FI.......
