I guess this could go in buying advice, but it's also pretty specific to hardware. I've just discovered my Dual 2GHz G5 needs a new Logic Board (or so claim the Authorized Repair people). With this likely to be a few hundred pounds, is it worth replacing? Is it likely something else may go wrong, does it indicate the start of more problems? Anyone else found this and wish they'd just got a new machine instead? It's a Oct 2003 model, so quite early in Dual G5 line, but had been working flawlessly until then. I just didn't notice 5 years go by as it ran like new. I was actually contemplating getting a MacBook Pro (same speed, portability and Intel chips) and selling my G5 to part fund it, then this happened! If I don't replace the board is their any way to get some value out of the remaining bits? - I have 2.5Gb ram and an additional 500gb HD. Thankfully I have an external HD for my Time Machine! Any advice would be great. Edit: just realised I join MR when I got that machine!
