friends i want to know Which one ATI FirePro v4900 ro Nvidia Quadro 2000? one more thing is that if i goes with ATI i want to be sure that its compatibility with Maya 2012/13, Zbrush4rb, 3ds Max, cause i hard some issue with Maya.
most of all rendering part belong with CPU but, i also want to know that did now new generation cards are help full in fast rendering if some have and information or know video so send me link of that. because my main motive to purchase
GPU is fast rendering so i can work fast.
as you write that ati hand may well but i want to u look this link http://devgurus.amd.com/message/1224901. recently in our designing institute I MAC which have ATI redone 6570 GPU Maya 2011 working slow.
when u looking more deep u will be find out ATI problems http://www.youtube.com/watch?v=psitkceRupE this link about ATI FirePro v4900. if you type in Google ATI firepro compatibility issue with maya. i think ATI need proper hardware support is drivers.
but i looking something and according to information
Quadro CUDA vs FirePro Eyefinity Technology not Open CL
both card support Open CL and GL this is display preview technology
and if some on spend 400$ to 500$ on GPU for old pc like mine it is batter buy new core i7 3rd generation with good motherboard.
cause i tested with my maya file render on Corei7 2600 with nvidia geforce 8400 and its twice fast render giants may pc.
so i decide that i will be go with FirePro V3800, V4800, V4900 or Quadro 600(not spend to much on it
one more question dose DDR3 vs GDDR5 make big different?
I realize that this doesn't perfectly reflect workstation graphics performance (which these cards are tuned for) but it's a good way to compare cards.
Just thought I'd let you know. Currently the 4900 and the 4800 are very close in price (on Amazon) so go for the 4900 if you're choosing between those two.
One thing to note is that the Quadro 2000 is rated as 25% slower than the 4900, in the above benchmark. Again, this doesn't reflect performance in a production environment, which is highly dependent on drivers and optimization, but it's something to keep in mind.
