@ keyclone & matt, thanks for the input! It was great to see such a quick response to what are probably pretty dumb questions

@ matt: yep, the Core 2 Extreme is a quad-core processor, though I'm not sure the difference (mechnically at least) with the processor that you have.

I'm thinking of switching my WoWing over to the Vista Ultimate 64x environment b/c it seems to be better suited to utilize my hardware. Given that XP can only use ~3.2 GB of my RAM, I figure that might help with some of the choppiness I'm seeing in my other wow client.

At risk of sounding like an idiot, I've got a few more questions:

1) what does maxfpsbk stand for exactly? (I'm assuming the max frames per sec for the back/non-focus window?) Also, in my current maximizer setup, I have the maxfpsbk value set for 25 on each respective WoW client. Should they be set to different values for my main's WoW window and my helper/alt WoW window? Or is setting the same value throughout my various client windows appropriate?

2) I tried to play around with getting a 2nd monitor set up (I had an old SyncMaster 930B that was gathering dust in a closet) but ran into the problem of having two displays at different resolutions. My 24" Dell is set to 1920x1200 while the Syncmaster can (at max res) only get to 1280x1024. I ran each monitor from a different DVI port on my 8800 GTX, but couldnt figure out a way to make them both work unless I scaled the 24" widescreen down to the lower matching resolution. Are there Nvidia software/utilities to help with this problem, or does this mean that I'm kind of shoehorned into either a) getting another widescreen monitor or b) using the lower res for my larger display?

3) Assuming that my maximizer fps and fpsbk values are set to 50 and 25 respectively for both my main's window and my alt's window, is it normal for the non-focus WoW window to be choppier than the focused window? Whenever I'm manipulating my UI or looking around the game world, whichever WoW client that I don't have selected as my focus window is slightly choppier than the focus window. I'm just kind of wondering if this is normal.

4) I've was also looking at the Nvidia tweaking utility nTune last night. While I haven't run it yet, I was thinking that perhaps I could smooth out some of the frame rates I've been having by letting the software do a small overclock on my processor and my video card. Excluding the risk of voiding the warranty by overclocking, does this seem like a reasonable way to increase performance, or would the performance gains from the overclock probably not really be that noticeable?

Thanks again folks!
