greetings all! i have been a windows user for years now, although at my last job i worked on a G5 and loved it. i have been researching converting over to a mac recently, but am wondering if i am looking into buying the right thing. i have dual monitors that i will use on my mac, so i only need the tower. the used G5 seems to be a great deal, as i would like to stay in the $1500 range. i am a graphic designer and use photoshop, illustrator, etc. this one for example seems great: Apple Computer Power Mac G5 Desktop Dual 2.7 GHz - Apple Computer M9749LL/A memory: 2G 120GB HD am i understanding that a min of 2.7GHz and min of 2G memory are the two main things that i need to focus on as far as speed and reliability for graphics programs? and also, that needed graphics card is already installed on a G5? much thanks in advance! i feel as though i am flying blind, and every post i see references a laptop!
