I haven't posted in a while, but with the advent of tiger and the saving of a little more money I am close to buying a Mac. Now, I have changed my original idea of getting a 12-inch PowerBook, because, while it is small, fast, and sleek, I prefer something bigger and have come to realize a desktop suits me better then a laptop anyway. Now I like to work in Photoshop a lot. Its my hobby and I'm pretty serious about it. I don't want to buy a G5 tower because they are very expensive, though I get an academic discount on everything I buy. I'm leaning towards a 20-inch iMac. Now, I know if I fill it up with a full GB of RAM (as I planned to do with the PowerBook), then it will be faster then the PowerBook. After all, it does have a bigger hard drive, the same graphics card (for now, rumor sites seem to indicate an imminent upgrade), and most importantly a faster G5 chip. Someone correct me if I'm wrong in assuming the iMac is faster, because it seems that it would be faster. So my question is this - if I were to buy the 20-inch iMac and outfit it with the GB of RAM, would it be fast enough to run Photoshop efficiently? And if so, what site can I get memory from, cheap? MemoryToGo is not an option because it reveals credit card information on non-encrypted pages. Kinda unsafe. Please share your thoughts. Oh and the Tiger release at Tyson's Corner was great!
