I think I just wasted $1000 on upgrades (Vista64, 8GB Ram, Dual 9800gtx)

I thought I read somewhere that there is a driver problem where the 2nd card's renderer will actually not be utilized at all. I don't know if this is true or not.

Nitro, did you end up pulling half your RAM?

WoW doesn't use DX10.

Right but like I said, all I could find relating to this. Would be nice to know why 2 video cards + 2 monitors = same performance or worse performance as 1 video card driving two monitors.

Na, all 8Gb and both vid card are still in the rig even though im not using it all. I still have my vista 64bit partition incase i need to use it for another game or something.

Just thought I'd chime in here - since patch 2.4 I've seen a big drop in FPS on my main PC. My other PC's still run fine, but on my main in Shat & Sunwell I get 10-12 FPS consistantly. Pre-patch I was getting 50-60 no problemo. If you have a look through the WoW Tech Support forum, you see lots of posts mentioning either big drops in FPS, or outright crashing. I am 100% WoW is culprit - I can play other games like Crysis without any problem at all
BTW my system specs are:
2.4Ghz quad core CPU
4GB RAM
8800GTX 768MB RAM
