8 core macpros

January 28, 2008 | 11:16 am

did anybody get a chance to test the new 8 core mac pros .
any remarks , recommandations regarding graphic cards and how to take full advantage of the processors ?
they come with the ATI Radeon HD 2600 XT 256MB, apparently the only 512mb available card for these machines is the NVIDIA GeForce 8800 GT 512MB GDDR3. what would you recommand?
they will be used to mainly manipulate/display high resolution movies/textures .

any feedback is very welcome thanks in advance :)

they are ferocious machines.

mixing two streams of pjpeg 1080×653 video lossless quality and
reading a unibrain camera at 640×480 at the same time for frame
difference tracking still gave me 45fps with the baseline card. no
need to wait for the geforce.

sounds goood :)
how heavy are your files in general ?
are there any recommandations for reading heavy files , 1GB and above ? wouldnit be better to split the files into smaller ones.

i tried on a quad core machine reading a 1440×900 photojpeg/high/25fps compression ( and all the optimizations required on the jitter-openGl end) whereas quicktime reads it perfectly smoothly.
am i being a little pushy ? :)

ultimate size of the file never matters if you’re not reading from RAM.
