I just talked my friend out of buying a 3 ghz PC into getting a G5. But he wants to know which is better a Dual 1.25ghz powermac G4 with 512 ram, 80 gig HD, combo drive, Nvidia ge force 4 ti, and a 20 inch studio display or a 1.6 G5 with 512 ram, 80 gig HD, combo drive, ati radeon 9800 with a 20 inch studio display? The G5 is only a few hundred dollars more. He want to be able to play all the best games including Doom3 when released. He wont be using it for any editing or anything else besides maybe some photoshop, music, internet, and papers. What should i tell him to get? I was under the assumption that the G5 was all around better for his purposes than the juiced up G4. What will perform better when it comes to games? What does a 1.6 ghz G5 equal in terms of ghz in the PC world?
