the asus mars is just a ridiculous experiment.

the only thing a gtx490 could be is dual gf104.

and with the right chips it could compete well with 5970. it doesnt have to beat 5970 at everything. it will cost less to make than 5970, so even if it is slower half the time, they can afford to undercut the 5970 price to make it fair.

they are collecting and binning the gf104 parts by function and voltage right now. they have them piling up. YOU guess what they are going to use them for.
