Hi, Here is a test I did in Photoshop 7.0 and LightWave 3D 7.5 rendering These are not benchmarks or anything tech, just really "monkeying" around. Out of the box G5-1.6Ghz Single Processor upgraded to 1Gb of RAM (you know the rest of the specs). AMD Athlon XP 1.7Ghz (14 months old) with 1GB of PC2700 RAM and nVIDIA Quadro 4 750XGL Card, from xicomputer I also have other machines here, Dual Xeons 2.4's and 2.8's with Quadro 980 cards from BoxxTech and Dell, as well as one Dual AMD Opteron (64bit) 244 with Quadra FX1000 card from xicomputer. I decided to test G5 against the slowest PC I'm using, the 1.7Ghz single processor AMD XP running WIN XP Pro. I'm not going to go into Photoshop tests details, but it involved manipulating a 50" x 50" RGB image at 72 dpi. That's a 37.1 MB file. I did all kinds of things a power Photoshop user would do or does on a daily basis. On average G5-1.6Ghz was anywhere between 4 times slower to only 15%-25% slower. I think the worst was when I ceated new layer, applied render clouds and rotated it 45 degrees. G5 took 6 seconds to render clouds, and 21 sec to rotate, where AMD XP 1.7 tool 1.8sec to render clouds and 9 seconds to rotate. I did bunch of other things involving scaling, rotating, applying some filters, copying layers 10 times, linking them, rotating scaling again. I really expected G5 to catch up to AMD's but no luck in this case. The render I setup in LightWave 3D took 2:47 on G5 1.6, 1:50 on AMD XP 1.7 and just for kicks Dual AMD Opteron rendered it in 28 seconds, that's only with 512MB RAM cause 4GB RAM upgrade hasn't arrived yet. I'm looking forward to test Dual G5 - 2Ghz. thanks for reading PS. I am a MAC user (since early 90's), I was forced to start using PC's mainly cause of performance issues in 3D work, and I really like OSX.
