I build and sell custom PC's to people in my free time.
today I got a question that I just had no idea how to answer.

"if I get 2 6800 ultras, each has 256 megs right, so does that mean I'd have 512 megs of videocard ram?"

I had never thought of that...
so I have no idea how to answer it.
but it did bring up a interesting question to me.
if it does mean you get 512 megs of videocard ram...
will it be just as good as a single card with 512 ram (when it happens)
will games be able to use the 512, like doom 3?

how would it affect benchmarks?

kinda embarassing to be asked something, and draw a complete blank....
