Ok I am no computer expert and I need some advice. I am playing 5 wows on one machine using keyclone. In BC I never had any problem with lag. I use a small number of add ons and have my grahics settings very low. Leveling in wotlk was not too bad until I hit dalaran and other places that contained a ton of people Even a 10man raid sends my games into choppy sinclair mode. In order for me to continue playing this game I think there needs to be some upgrading.

Here is a list of my computers specs....

Intel Q6600 Processor
8gig Corsair Dominator DDR ram
Asus P5w dh deluxe mb (pretty old)
Vista 64
Seagate Barracuda 500g drive ( right now I use 1 wow directory located on this drive)
WD Raptor 150g drive ( this use to be my main drive until I changed from XP to vista 64)
2 ATI 3870 512meg video cards (not in crossfire)
3 LCD monitors ( 24 main and 2 20inch sides)


This setup worked fine in BC. However, its damn near impossible to play in some areas. In the bg's it can get pretty choppy making game play even more frustrating. If you tech guys know how I can improve my game performance let me know.
