Mac or pc for photography work

Having a fairly ok PC and a pretty new macbook (2.6ghz, osx 10.5)

I can say quite simply that PC is your best option.

CS3 works extremely well on any dual core processor compared to previous versions. Its plenty fast enough even on basic entry level machines which are all now like 2ghz dual core and above.

I would reccomend you get a PC with the best processor and the most amount of good fast ram that you can afford, this will work out a hell of a lot cheaper than PC, and youll get an extremely high spec, fast fast rig.

I think this is what im going to do, iv been reading some reviews of the Mac mini and they all seem to say that its pretty slow with a small hard drive and cant really be upgraded.
To buy a mini new would be around £500 for the faster version and for this money i think i could get my mate to build me a much faster pc and get some software for it.
