![]() Replacing the Ati Rage card with this “new” Radeon turned the PowerMac into a very usable machine, multitasking and all. I went for it, and yesterday morning the card arrived in the mail. Someone had a Radeon 8500 with 64MB of video RAM on offer for just 30EUR, which in Mac land isn’t a whole lot. A few days ago, I finally spotted a decent offer on, a website dedicated solely to selling/buying second hand Apple stuff. ![]() So, ever since I bought the machine, I was on the look-out for a nice Mac graphics card that was Quartz Extreme capable, which should deliver a serious speed boost for the PowerMac. The biggest issue was a lack of a Quartz Extreme capable video card, which meant that all the animations and window drawing and such were done by the processors, putting a lot of extra strain on the already ageing G4s. It ran Mac OS X 10.4 Tiger, and it did so fairly well. The community soon found ways around this limitation, and recently, I found myself in a situation where I had to do the same.Ībout half a year ago, I bought a PowerMac Dual G4-450Mhz, with 1GB of RAM. Back when Apple introduced Mac OS X 10.5 Leopard, there was a bit of a minor controversy around the artificially implemented cut-off point you could only install Leopard on machines with G4 processors of 867Mhz or more, leaving out capable machines like the dual 733Mhz or dual 800Mhz.
