The Driverheaven Photoshop Bench v2 is a benchmark that utilises Adobe Photoshop for its tests. I believe it best represents real world results which are useful for graphic professionals or any Photoshop user.

Download here: http://www.driverheaven.net/photoshop/dhpsbench2.zip
You will need to have Adobe Photoshop CS2 to run this test. The download is just a test image and a Photoshop action.

My results from Adobe Photoshop CS2 on a Core 2 Duo E6600 with 2GB DDR2-667 in OS X 10.4.7. Computer specs in my .sig. All results are in seconds so lower is better.

How do you insert tabs in this editor?

That's very interesting topic for me. I was looking for a topic here, and i wanted to post another Benchmark test, that test's CS3 by now.
But for now here are my results on my new Toy.

Results are from Photoshop CS3beta, in my E6400 stock speed, with onboard GMA950.

Using the same test on CS2 on my XP machine (E6300), speed was 15% better, but that maybe due to the Raptor HDD i have on the XP machine.
This OsX86 machine uses a Samsung HD400LJ HDD

Photoshop CS2 Test (PPC-Rosetta), UB CS3 looks really fast. I need to upgrade. Are there any stability issues or compatibility problems for any of you CS3 users?

Hey, I wanted to try out this test as well but I cannot download the test. What's the deal?

Hi there,
You need to go to the website and scroll about 1/4 down and look for "Macintosh friendly ZIP version here." in the text. They seem to have some sort of protection when your referral is not from their website...

Does anyone know what additional directories need to be copied when copying PS3 from another MAC? I guess something in /Library/Application Support/Adobe*, but anything else?

I am running 10.4.8 with semthex 8.8.1 kernel and CS3.
Gigabyte GA-965P-S3 mobo, Intel Core 2 Duo E6400 2.13 Ghz, two sticks RAM of 512mb each, ATI X1600 256mb Pro

As far as stability issues, I have not had a problem. Way better than CS2.

Here are my scores:

Texturiser Test 1.2
CMYK Conversion 2.0
RGB Conversion 2.7
Dust & Scratches 2.9
Watercolor 16.5
Texturiser 2.0
Stained Glass 4.4
Lighting Effects 6.7
Mosaic Tiles 16.4
Extrude 52.1
Smart Blur 73.5
Underpainting 23.2
Total 203.6

Finally got CS3, it's much faster I can see. About 120secs difference, halving my CS2 times. Can't wait for it to go final.

Err..guess I pushed + a few too many times on the calc.

I upgraded my CPU from Venice 3000+ to San Diego 4000+ and my PS3 score went from 365.4 to 255.8. My xbench from 84 to 110!
