dude ;( just wait for the offical reviews... these are just numbers without any screenshots... also 3D mark don't really mean crap

i like to see IQ test.
i will break it down for you "technoob" :
SLI vs crossfire
ATI X1900XT + ATi X1900 XT 512MB CrossFire = 13,501 3DMarks for $1098
2x NVIDIA GeForce 7900 512MB SLI = 13,000 3DMarks or its not SLI

if its not sli then this card would kill aTi alone unless nvidia wants to play the 7800GTX 512MB game again...
card by themself
ATi RADEON X1900 XTX 512MB = 11,149 3DMarks for $649
ATi RADEON X1900 XT 512MB = 10,000 3DMarks for $549
i think these score are made up and we should wait for offical review and then wait a month more than price would come to down to normal levels
