Sweet
no, one controller can address two moduels at once in clamshell. It means that one gpu could potentially write to another's framebuffer. AS noted in the pic above, clamshell only allows for doubling the buffer size. You could run into page conflicts when two memory controllers each address the same pcs of GDDR5.
Yes, got my epeen alright.Got E-peen, Cadaveca ?
When the prices for GDDR5 go down a bit, you will see 1GB cards. You can also crossfire two 4850s if you need 1GB that badly, and most people that have a $1000 to spend on a monitor usually do go xfire and sli, so again, your concern is a tad unfounded.

Um, Perkam, I've got 3870x2's...two of 'em...512mb framebuffer for each gpu, 1gb for each card, and it's not enough for 2560x1600.
Unfounded? lol. You look really out of place now, don't you? Remember, I'm the guy buying high-end parts on release...I'm the one that has those concerns.
You, on the other hand, buy entry-level parts, so I understand your perspective, but you should also understand mine, rather than trying to undermine it, and you should also face reality a bit here.
I'm the ATI fanboi...I'm not knocking the products, merely highlighting my needs as an extreme enthusiast. Surely you can understand that?
