would you consider a factory recertified if it was a really good deal....
I think most PC's with Intel Pentiums are dual core, there are also a bunch of Quad Core, but I don't think you get as much out of that. I have the Quad Core 2.66 mHz with 2 350 internal hard drives and 3GB ram upgradeable to 8. It runs great for me, though I probably will up my ram sometime next year. My camera files are twice they size now as they were with my previous camera so the extra RAM will help.
You may also want an exteranl HD. I have 2. When I download the images from my memory card I have them downloaded to 1 of the internal HD's AND 1 of the external HD's. Every month or so I also send a 3rd backup copy to the 2nd external HD along with making DVD copies. So you'll want a DVD burner too. Having dual monitor outputs is nice to have as well. I use a 22" widescreen monitor, but I also send a signal out of the 32" HDTV in the living room for easy viewing for the family (also works nicely when you want to watch video's from the internet, especially from ABC.com and other networks that have full video and/or HD programing availble to watch online)
If you have an apple store near you, you owe it to yourself to check them out. for all the things mentioned, an Imac has most of them and if you want it for pictures, etc, I think there is no better.
I still have a pc at home but also have an Imac and a mac laptop. When the pc dies, I am not certain I will get a new one.
Wouldn't going with a Mac also mean that you would have to re-invest in expensive software that you already have for a pc? You might want to wait until the next version of Windows comes out. It is already being talked about and seems to be an improvement over Vista.
I'm a recent Mac convert as well, and most of the software I use came with both Windows and Mac versions (Capture NX, Lightroom, etc.) I haven't had to buy anything new. Not only that, Capture NX runs much better (i.e., faster and it doesn't crash) on my Macbook than it did on my pc, which had a faster processor. I haven't used LR much since my switch, but my brief experience with it suggests a similar result. IMO, the Mac OS is worth the extra $$.
Mac hardware = PC hardware, it's all the same parts. The difference is in the software and the price, and I can't see paying the extra $$$.
For a photo PC you are best off building one. It should have a fast processor, separate system and application (and scratch) drives, a decent video card (but not a 3d gaming card), and lots of RAM, although I see little chance of using more than 3 or 4 GB for photo work.
A good power supply, such as PC Power & Cooling helps keep the system stable.
Building a system does not mean you have to do the work yourself, a place such as Puget Systems will assemble a PC to your specifications. This way you get what you want without paying for what you don't want.
What about the people that purchased by download? Are they allowed to download the trial in Mac and then enter the registration code to make it work? I am not saying you have the answers, I just want to throw that out for those interested b/c I do not know.
While it is all out there for the OP, why not also consider Linux? I would say it is more stable than Win or Mac. There might not be the software available for it though.
My dh is a Linux guy. His view is that Linux is the best OS, followed by Mac, with Microsoft a distant third. Though I've seen him eyeing my Macbook with envy lately, so maybe he's thinking of altering that ranking.Unfortunately, most of the software we use isn't available for Linux. Dh did find some free photo editor that he uses on occasion, but I think it's pretty limited in terms of its features.
