My old G5 tower died a while back and instead of spending money on it and I'm thinking of replacing it. I just read this MacWorld Article from 2009. See quote below. A recent MacWorld shows the top 3 iMacs virtually equivalent in speed to the 8 core MacPro. Is this a no-brainer? In the iMac department, I'd have to check individual specs but I would tend towards the i5/2.7Ghz 21.5" iMac (speed mark 229) and save my self $500 over the 27" if I can get 1Gb vram video card in it. update: I just checked. There does not seem to be a 1GB video card available for the 21" model. I assume it would be a gaming mistake not to insist on that as compared to 512mb card? Are there any other issues to consider in this purchase? Is there an outlet that would purchase a G5 tower? I hate to throw it out although I can recycle it. It's just too pretty. For anyone who feels the need to tell me to get a PC, I all ready know all about them. Thanks!
