After a lot of serious thought, I have decided that instead of purchasing a PowerMac G5 this summer, I'll just shell out some cash here and there and upgrade this old 400MHz G4 and make it my secondary computer. Since my mini is now plugged into my TV full-time, I need something at my desk . Currently the system specs are as follows. PowerMac G4 (AGP Graphics) CPU: 400MHz G4 RAM: 896MB Graphics Card: (PC-flashed) Radeon 7000 64MB VRAM OS: 10.4.11 Tiger What I would like to get out of this machine after upgrades are as follows: -Run OS X 10.5 Leopard at a decent speed. -Run iWork '09 steadily. -Browse the web with Safari (I absolutely hate TenFourFox!). -Play Late 90's and Early 00's games mainly around medium settings in both OS X and OS 9 (Call of Duty 1, 2, other FPS) I know I need to max out the RAM to 2GB, but I don't know which CPU or graphics card to purchase that would suit my needs. How powerful of a CPU do I need to perform these tasks? 1GHz? More? What is the best graphics card for the my AGP G4 when it comes to PPC gaming? The ATI 9800?
