New to multi-boxing

Will this system handle 5 boxing? I plan to upgrade to 12 gigs of ram. Also when I say handle meaning dalaran wont be a lagfest. I would like to still be able to run 5 through dalaran and stay above 20-30 fps just dont wanna buy a pc then fine out it can only handle 3 or so if you know what I mean.

It should work great. I would check how the memory is set up and how many open slots you have. If it is full to get to 6 gigs, you have to throw that RAM out to get to 12. The other parts are top notch/ high priced gear.

it has 3 available slots and ty for the reply

good, that way you just add 3- 2gig sticks. I suggest you do it when you buy the system as it is best if all your RAM matches. Other than that small thing, I am drooling over the system.
