Upgrading a Nvidia card to a Ati card?

[DeeBye]

On my 32-bit XP only a little more than half a gig of video card memory is mapped into the system address space. Why it all isn't I don't know.

Well I just installed the new card and it shows the same thing.



I have 4GB of system RAM and the videocard has 1GB, but Windows shows 3.5GB. It is a mystery.

As a humorous sidenote, my 7 year old son saw me unpackage the HD4890 and said "Wow that is big! It's bigger than my foot! Not your foot though, because you have big feet."
