Good Enough for 5? What do i need to improve?

Hi I'm about to start 5 Boxing and was about to change computers to accomodate my 5 boxing demands however i have come across a few issues resulting in my computer not being ready till late july.
Now a few questions im currently 3 boxing on a Macbook Intel Core 2 Duo with a 2ghz processor and just 1G of RAM! Its got a sub par video card which is a GMA x3100. Are these specs good enough for 5-Boxing, I 3-box fine (apart from in main cities)
on my current setup and would love to start 5 Asap.
What should i do?
Thanks in advance for the Help

welll go ahead and try out the 5 boxing.. and see how much it lags. I am not sure how much ram ur computer can hold, but i upgraded from 1 to 8 gig.. my computer runs 4 easy even in most cities and it has worse specs that urs

If u turn off the sound .. it might run smoother for u.

I'd definitely get more RAM. I'm not sure about yours, but my WoW running at lowest settings uses about 250MB, so if you were running 5x that, you're going to exceed your 1GB big time.
