Hello recording gurus. I've decided to re-build my recording studio. I was initially a PC guy and decided to convert to a MAC. Due to financial setbacks, I'm limited to purchase an older mac. I've came across both a G5 dual 2.3 ghz, 250 gb, and 3.5 gb RAM for $180. Seller used the platform for mixing electronica music. He has pro tools and logic preinstalled. The second mac is a G5 quad 2.5 ghz, 4 gb RAM, 2 500 gb external hardrives, and a fresh install of pro tools LE. This bad boy is going for $350 (with a keyboard, and mouse). I probably won't upgrade to a higher end mac for a while. Is the 2.3 dual core sufficient, or should i fork over the extra money? any additional info would be appreciated. Thanks in advanced guys. Cheers!
