Since IÃ‚Â´m into cutting and converting videos and such I was thinking..

Dont know if you know this but you can transcode video with your GPU SPÃ‚Â´s if its not too old and much faster than with a multicore cpu

I got 2x 8800GT 512mb (112 Stream Processors)

I'm wondering coz iÃ‚Â´d like to compare notes on the transcoding speed difference between nivdia and ati cards

its all done with the streamprocessors on the card, nvida SPÃ‚Â´s are usually faster at this (more optimized) than ATi but Ati has usually more SP's on theyr cards so its difficult to know what card is better than than another.

for example then on my 8800GT 512 I have 112 SPÃ‚Â´s and they transcode a 700mb file in 6-12 minutes (mostly depending on the length of the video) while it's taking maybe 40minutes on my 4core Q6600 Razz

the newest nvida cards have 240 SPÃ‚Â´s and the latest Ati cards have 1600 SPÃ‚Â´s

nvidias program is called Badaboom http://en.wikipedia.org/wiki/Elemental_Technologies,_Inc.

and AtiÃ‚Â´s is called Avivo http://en.wikipedia.org/wiki/ATI_Avivo and its free

I dont include X2 (2 GPUÃ‚Â´s) cards in the list as they dont work in parallel when trans-coding you can only use one of the GPU for any 1 Trans-coding job, so lets say you have 4 cards (then id recommend having atleast a 4core cpu also) in your machine then you could be trans-coding 4 videos at the same time finishing transcoding a whole season of some episodes in less than a hour Wink

though I'd not recommend it for a too long time as I have had my machine freeze when putting a heavy load like that on it and then if I dont repeatedly hit cancel on atleast one job it crashes and can potentially damage the cards if not more :S

also here is a nice overall comparison chart though not the latest cards on it
