Hi, I have recently started photography and picked up a canon 500d dlsr. I am shooting in 15MP Raws which tend to be around 23MB each. I am editing about 100-200 a week of these in photoshop on my Mac Pro Quad 2.66ghz with 2 640GB drives in raid 0 and a 1TB backup disk. I only have 3GB ram and can't really afford to upgrade it yet, but when I am editing it seems laggy as hell! Also my iPhoto library is almost 100GB and takes about 10 years for each photo to load, is there any way to speed up my system or a better way to edit or organise my photos than Photoshop CS4 and iPhoto? Thanks Sorry about the long post!!!
