Just wanted some input on this. There is a Power Mac G5 Quad Core for sale locally (seller is legit) and I'm wondering how much I should pay for it. Specs: Quad Core 2.5 GHZ 4GB RAM 250GB hard drive He's asking $600. I'd basically be using this as an internet machine at home. This machine may be overkill for that purpose, but I'm currently on a 1.8 dual core G5, and there are certain things on the internet that it can't keep up with, like high-def videos. I just want something that can handle anything the internet has to throw at it, with room to spare. And yeah, I'll be stuck on Leopard and limited to whatever software it can run, which is fine, I don't need the latest of everything. Looking forward to your opinions. Thanks.
