With Doom III just around the corner, I'm sure a lot of us are thinking of ways to upgrade our systems to get the most out of the game. I currently have a 1.6GHz PowerMac G5, with the OEM 64MB Radeon 9600 Pro graphics card. The 64MB Radeon 9600 Pro handles most games OK, but I'm thinking the 128MB or 256MB Radeon 9800 Pro would handle them better . My question is, are there any 1.6GHz G5 owners out there who have a Radeon 9800 Pro in their system? I'm looking for some benchmarks and performance impressions on how 9800 performs in the bottom-end 1.6GHz G5. I know there are benchmarks out there for the higher-end G5s and the Radeon 9800, but I want to be sure that the single 1.6GHz G5 can effectively supply the Radeon 9800 with enough data to make the upgrade worthwhile (ie: I want to make sure a single 1.6GHz G5 won't be the bottleneck). That said, would anyone be interested in buying the 64MB Radeon 9600 Pro from my G5 if I did eventually upgrade?
