After Effects can take advantage of multiple processors even without the use of Render Multiple Frames Simultaneously multiprocessing. Because After Effects is multithreaded, it can also spread the processing of a single frame across mutliple processors. So, more processor cores is a good thing.
More RAM is also a good thing, in part because of longer RAM previews.
The details of the GPU don't matter much for After Effects, as long as you meet the minimum requirements. (Premiere Pro CS5 is another story; it can take advantage of the GPU and really performs better on the higher-end cards.)
Thanks for the clear answer on the cpu

Well... The Quadro CX was making a difference!
Plus, if you have a look here ( http://www.nvidia.co.uk/object/adobe_AftereffectsCS5_uk.html ), the Camera Zoom & the 3D Animation Rendering seems to be really affected. Well my question about the gpu is... can we trust those videos?
The 3D viewport rendering, the DOF management and the handling of some other stuff... worth it for me. Especially if it's accelerated like in those video. the real point is: does the quadro FX4800 is as efficient in AE CS5 as the Quadro CX was for AE CS4?
Actually, I have a gforce 8800 gts² who meets the minimum requirements. Anyway, using opengl is useless or only a source of errors & crashes. Add it the fact that the interface become really choppy as soon as i have a lots of layers displayed in the timeline, I'd like to know if using a quadro will do a real difference by providing a real pro solution...
Come on. Anybody can't answer my upper question?
OpenGL features have not changed in CS5, so any performance gains and improvements would solely depend on the card's configuration or driver config. Whether or not those come into play would still depend on your workflow. The only real difference then would be the cards' memory outfit and clock speeds, which may give you a few extra microseconds here and there, but nothing to write home about. Of course more memory in the card will also neatly avoid texture and shadow map errors, if that's of any importance. The only other thing that is partially accelerated is decoding of certain footage types. If you use AVCHD and similar formats, you may see notable differences. And let's not forget about third-party plug-ins... The rest is neither here nor there, as they say. It's not necessarily always the most expensive card that offers the best bang for the buck. I for one am quite satisfied with my GTX 285, but then again I rarely use OpenGL acceleration in AE itself. It handles CUDA nicely, which is becoming more and more popular wit hsome third-party plug-ins and plug-ins like Magic Bullet Looks, that also use OpenGL, work relaibly. That's all I can say about the matter.
Thanks for replying Myllenium.
Currently I'm aware that quadro wasn't making a big bang in AE.
I have a gtx285 here too (@ home it's a 8800 GTS²) and yeah, I rarely enable OPENGL because, well... it's quite unstable and not so faster.But it's gtx285, a gaming card.
Anyway since the Quadro CX, the rules seems to have been modified.
If the CX was still available, I wouldn't insist that way, and for now, I'm just wanting to know if the videos I've posted here is Nvidia Marketing's bullsh*t or not.
Okay I found a starting of answer...
OpenGL in After Effects can render the following features:
Shadows, except point light shadows (Colored shadows appear gray.)
Lights (eight maximum)
Transformations for 2D and 3D layers
GPU-accelerated effects, including Bevel Alpha, Bilateral Blur, Box Blur, Brightness & Contrast, Channel Blur, Color Balance, Color Balance (HLS), Curves, Directional Blur, Drop Shadow, Fast Blur, Find Edges, Fractal Noise, Gaussian Blur, Hue/Saturation, Invert, Noise, Radial Blur, Ramp, Sharpen, Tint, and Turbulent Noise
All blending modes except Dissolve and Dancing Dissolve
Metal property settings for 3D layers
Cone feather settings for light layers
2D motion blur
That's still a lot of frequently used things. So it may worth it. I guess that using quadro instead of geforce will improve stability.
And i guess that using High End quadro instead of geforce will provide faster answer....
Anyway, if anybody have experienced the FX4800 into AE and compare it to the video posted on the nvidia website... that would be great....
Because the real question now, is to know if a Quadro could challenge a bi high end cpu computing... if no, or not so much, quadro are definitly not interresting for AE in this case.
