I'm looking to upgrade GPU in 2005 power-mac g5 however even though i can find many threads online talking about the subject I'm finding it hard to narrow down which cards can actually be flashed to work with the power-mac g5 or just work straight out of the box. I do know of a few that will work 100% but they all seem to be ridiculous prices on eBay. Any advice will be appreciated or maybe just send me a link to where i can find the information I'm looking for thank you.
