Wow I had typed out this nice message, but when I submited it didn't go, and then when I went back it was gone. I freakin' hate that.



Long story short:
Ram--
Goto shatt with all 5 of your characters, then check your available physical memory. If you have less than 100mb left, I would get the extra gig (even though it will only give you .3 gb more).

Gfx--
I leveled to 70 with a radeon x800 xl 256mb gfx card. Your gfx card will be fine for that. I am unhappy with my framerate in arena/bg's so I just bought an upgrade which is in the mail. Wait until you get to 70 then see how you like your framerates and upgrade if you don't like them.
