Thanks for the reply, but as you see I already found my answer.
I know about the specs on the card, it's for a casual gamer so I don't need anything fancy (he had onboard video before so this is still better).
But the MX440 can have 32bit (although I've never seen one), 64bit or 128bit memory width. The difference between 64bit and 128bit is very large so that's why I wanted to get a 128bit one.
back to the store with this 64bit piece o crap
