I'm wondering where I need to start upgrading. its been fine up till now on azeroth, however I'm having a hard time in shatt, I can only go a few steps and then have to wait on all the alts to catch up or they will loose follow because its so choppy, it was a little better at thrallmar but still choppy when I tried to kill some boars.

You can see my system specs in my link, I can put them here if needed. I'm running 2 alts off one core, 2 off another, and main off one, and leaving one for the system. I have main in one folder, and the alts in another folder. I have alts turned down in keyclone to 15 fps max. My ram graph on my keyboard is showing ~55% on cpu , and 98% of ram used.

So where should I start upgrading? I was thinking start off with a new gpu, but if I get another I'll have two, and was thinking maybe a good place to start would be put main on one monitor/ card, and put alts on the other monitor / card, but don't have the cards SLI linked? Or, will that not work and I'll just need to upgrade the one card.

If that doesn't work, I guess I will need to upgrade to Vista Ultimate 64 so I can buy 4 more gigs of ram and have 8 gigs of ram to see how that goes..

So what do you experts think?
