Guys,

I've been 5-boxing for a good while now, and my computer has done ok - But, Dalaran, PVP and even running around the Tournament area slows it to a craw and even causing frequent freezes on one or many wow clients.
The freezes become more frequent until I restart wow or even reboot - Typically, if I visit Dalaran, I benefit from a reboot of at least wow after that.
Most of the freezes are of the kind that I get them entering a new area, then as it has "stabilized" around that it moves better - But areas like running around the tournament in IC or dalaran are always extermely jerky and laggy.

So, I am firstly looking for advice how to invest in the current machine to get a bit more bang for the buck out of it, but I've come to terms that I will need a new one most likely.

So, I'm running:

Intel Core 2 Quad Q6600 @ 2,50 GHz
4 GB of Memory (which is max this motherboard can take)
2x 500 GB 7200 RPM discs, both quite full. WoW is ran from one disc, OS from the other (same as swap file), I run 2 folders of wow, one for main, one for the 4 slaves - All but UI and config data is linked.
A 8800GTS 640MB something no name graphics card - powerin 2x 22 inch Samsung monitors at 1680x1050, 32 bit color.

Maximizer in keyclone is set to 1-1 in game resolution,
Main wow is set to maxfpsbk 15 and maxfps 60
Slave wows are set to maxfpsbk 15 and maxfps 20

My main wow is set to the graphics settings I like playing with single boxing - which is fairly high spell effects etc to be able to see stuff on ground in raids etc and a resolution of 1600x900 24 bit color (60hz).
The slaves run the effects slider all the way on minimum, and 720x576, 24 bit color (60hz).

So, any advice that could improve my current setup? Mostly I would like to be able to pass through the IC torunament area without freezing and lagging.

I do realize I will eventually be getting a new box, but I'll start a new thread on advice about that.

Thanks guys!
