Workstation with Quadro 2000 or GTX 570 HD 2,5GB, for PP CS 5.5?

Question

Hey there,
I'm going to build up a new workstation for video-editing using the Production Premium Suite CS 5.5.
But there is still one big question and I can't find a proper answer.
What GPU should I take or which one will be faster? A Quadro 2000 or a GTX 570HD with 2,5GB?
I know the Quadro has 192 cores and the GTX has 480 cores. So the GTX should be faster
Actually? But would it really be faster? I can't find any Benchmark comparisons or stuff.
Some say a Quadro 2000 is better, if it's only a workstation. But I also read that people
Prefer the GTX-Models.
I know the GTX needs more energy and it's getting warmer when used, but those two facts
Wouldn't persuade me to buy the Quadro.
The rest of my system would look like this:
Intel Core i7-2600
ASRock Z68 Extreme 3 Gen. 3
G.Skill RipJaws-X DIMM Kit 16 GB
Crucial m4 128GB for OS, Programms
Western Digital AV-GP for the media-archive and the orginal videofiles
WD Caviar Green for Export and stuff like that
Fractal Design Arc
Scythne Katana 3
Super Flower Golden Green Pro 650 W
So the only missing thing is the GPU.
Thanks in advance for your help!

Answer 1

For the most part, I second Harm. You see, the AV-GP is not compatible with PCs at all - but rather, it's a version of the WD Caviar Green designed specifically for set-top DVRs/PVRs. And in either case, the current WD Greens spin at far slower than 7200 RPM - in fact, most current WD Green drives spin at only 5405 RPM (with a few spinning as slow as 4200 RPM). The slower rotational speed negatively affects both sequential transfer performance and random seek performance.
As for the non-K 2600, it is limited unlocked, not completely locked. There are two disadvantages to this limited unlock: Only the maximum single-core Turbo Boost multiplier is manually selectable, with the differing multi-core Turbo multipliers also increasing by the exact same number of steps as the single-core Turbo frequency (unlike on the K chips, the multi-core Turbo multipliers on the non-K chips cannot be set independently of the single-core Turbo multiplier). Second, the maximum Turbo multiplier setting is limited to four steps above the normal single-core Turbo multiplier: In the case of the 2600, the maximum single-core Turbo multiplier can be set at up to 42x (this will force the maximum quad-core multiplier to be boosted to 39x, which will result in a maximum quad-core overclock to 3.9GHz with the BCLK remaining at its stock 100MHz). The 2600K is so much easier to overclock the way the user wants it while costing only a few dollars more than the non-K 2600.
As for the original decision between the Quadro 2000 and the GTX 570, definitely the latter: The Quadro 2000, as far as CS5.5 is concerned, is little more than a slightly underclocked GeForce GTS 450 with a huge heatsink attached to it and still only 1GB of VRAM. And as Bill's testing with the various GeForce GPUs (to be specific, Bill tested the GTX 580, GTX 480, GTX 560 Ti 448, GTX 285, GTX 260, GTX 550 Ti and the 9500 GT, from fastest to slowest - however, the GTX 560 Ti 448 is roughly equal to the GTX 480 in performance) in CS5.5 has demonstrated, the Quadro 2000 would definitely be slower than a GTX 550 Ti, especially in MPEG-2 DVD encodes.
