I h8 you! X(

Just kidding!

I have a similar machine.

First, you need more RAM. That's by far your biggest problem. I have 4G (but run 32-bit XP atm, so only about 3G usable), and while it does suck in Shat, it's not nearly as bad as you describe.

Second, I wouldn't get another 8800gtx. For one thing, wow doesn't really deal with SLI well, and and SLI doesn't run over multiple monitors if you are running that way. For another thing, adding a second video card will actually subtract from your available ram once you get 4G. I tried this trade-off (more gpu power vs less RAM), and it was definitely not a positive one.

Last thing, maybe try a 64-bit OS (vista) which, when you upgrade to 4G, should let you actually use 4G. I am actually going to try this myself, just waiting on vista to arrive (tomorrow). With this, and 4G of RAM I'm hoping to have a better time in shat.

Also, you might consider an SSD drive as reviewed by silencer here. I ordered one of the 32G ones myself.

good luck
