I went into the Apple Store and tested the new 20" 2.4 GHz iMac with the ATI Radeon HD 2600 PRO GPU with 256 MB memory and 1 GB of RAM. It was the standard $1,499 model. I downloaded Vendetta Online and tested how many fps I could get at maximum settings in different situations. I compared the fps reading I took to what I can get using the same settings on my 4-5 year old 17" 1 GHz G4 eMac with the ATI Radeon 7500 GPU with 32 MB memory and 768 MB of RAM. These are approximate average fps readings that I gathered after playing for about 20 minutes. The results are as follows. Quiet Situation With Not Much Going On New iMac: 300 fps Old eMac: 50 fps Busy Situation With Lots Going On New iMac: 50 fps Old eMac: 8 fps A more detailed report of my basic test can be found here. Overall, I was very impressed. For a casual gamer playing an average 3D game, it was more than adequate. The game isn't a huge GPU/CPU hog, but it was the only thing I had time to download while at the store. You can look at the screenshots on their website to see the quality of the graphics (or download the free trial). It runs on older machines fine at lower settings but requires fairly new hardware to run well at higher settings. I'm hoping that other people can run similar tests and post them in this thread. Hopefully, we will soon have some official test results and benchmarks.
