While I am on vacation, I've been flipping through Craigslist for prospective Macs to work with and I found one, a G5 Dual Core 2.0 with 3.5 GB of RAM. After hauling it home, I did a basic cleaning but need some tools that I'll acquire later. I dropped in my older daily driver HD that ran Tiger. The Mac boots up and runs fine so far. It has the square power plug, PCI-E slots, and a GeForce 6600 video card worth 128MB VRAM. It will replace my Dual 2.0, which will go into storage. This Mac also came with an externally beat-up Cinema HD display with ADC adapter. The monitor has no back leg and I knew that going in. I am under the impression that a dual core machine will be faster than a dual processor machine. True?
