I have been interested in trying OSX for about a year now and waiting for the Intel systems to be released. Currently I run WinXP on my gaming system and Suse 10.0 64-bit on my laptop. I would like to purchase a new Apple Desktop to introduce me to OSX and Apple products. I was looking to get the new IMac 20'' with 2GB of ram, 256mb video upgrade and wireless keyboard and mouse. Or Power Mac Dual-Core PowerPC G5 Processor 2.3GHz system. I realize the Power Mac does not include a monitor but I can always pick one up. Which system would you recommend? I would like to perhaps game and get the most speed and performance at this time for running OSX. Thanks!
