I dun think R680 will lose 880gt, my personally think it'll beat 8800Ultra 100% for sure.. it might not be able to beat 9800x2 however, the gap wont be big.. Crossfire solution always does better than SLi ( nvidia SLi ) look back to 7950x2, is it very good card? after few years, 9800x2 is still a 2pcb in one card, whereas r680 is dual chip on single card. its power consumption is lower than 9800 and also quieter than 9800x2 ( compared r670 with G92, it must not the exact when it launch, just personal opinions )
this is the 1st card to hit over 1 Teraflop and 9800x2 will be the 2nd card..
3870x2 (r680) supports dx10.1 G92 doesn't support dx10.1, it supports dx10 only..
According to Nvidia they are not going to step into dx10.1, they will straight jump to dx11
G92 costing is already higher than R670, by the time they launch 9800x2 with old technology (still 2 pcb connected together) with higher price,
compare to newer technology like what ati is doing, and dun forget they support crossfire X, maybe x8 is possible in future too, dx 10.1, lower price..
and the price is even lower than 8800Ultra, which one will u choose??
but of course, things are uncertain now until they are launched..let's see;))
when is dx11 appearing in front of us?? few more years?
then in this period of time, games tat supports dx10.1 u can use ATi card to play:))
This card will launch at us date 23rd jan.. driver is ready *catalyst 8.1*
u haven't seem the r680 review yet??
of course, it'll launch on 23rd january.. review is not completed yet atm..
QUOTE
R680 very big size and design almost same to HD2900XT ......Using 55nm Processor.....more greater than 8800GTS 512mb G92 processor.....Can it beat Nvidia 9800? ...heh dunno yet ..cannot found info at web le.......
big size and design almost the same ??? bcoz it is dual chip on single PCB, then the size is big of course.. if u look into the cooler design and PCB design, it is totally different from 2900xt.. 3870x2 has got 2 chips on one board, its cooler also different from 2900xt, got 2 heatsinks..
