earlier time saw they predict the price will be USD549
now AMD already very clear that their r700 will be on top of the market, I don't think they'll sell cheaper than GTX280.. or maybe will be slightly lower
than the GTX280 after a while it's launched.

the power consumption is lower than 2 pcs of 4870 running crossfire mode.
have read the reviews, but don't know how true is it.. R700 with 2gb GDDR5 is not taking very big advantages because they only take very little higher than 4870 CF in most bench, some even lose to 4870CF.. 4870 is only using 512MB GDDR5.. Or what we can hope is their driver. Hope the upcoming driver will fix some problems..

600W should be enuf for single card.

will have 4850x2 uses gddr3
1gb version and 2gb version probably..

620 i think it's not a good idea to run 4870x2 CF.
I think 850W and above should be safe..
I'm using 800w, I'm also worried about my PSU whether can run..

grab this information from GURU3d..

4870x2 not even wining 15%..
not yet 15%
some test only less than 5% and some even
4870CF is still faster. it draws lesser power..
this is true.. If driver to be tuned finer in future,
you might see both CF and R700 gaining much
performances..
