iMac 20'' Graphics Card Comparisons

[dbam987]

I'm looking at getting a 20'' iMac, but am torn on whether the difference between the ATI graphics cards available on the two I'm looking at will make that much of a difference:

1. ATI Radeon HD 2400 XT with 128MB memory
2. ATI Radeon HD 2600 Pro with 256MB memory

Does anyone know if the performance between the two is drastically different? The 2600 version of the iMac has a 2.4 GHz processor while the 2400 one has a 2.0 GHz processor. It would be cool if Apple provided the option to choose the 2.0 GHz processor with the Radeon HD 2600 Pro graphics card, but they don't.

There is actually a reasonable difference in games. If you're going to do any gaming at all, I wouldn't recommend the 2400.

In everyday 2D use, there's no difference between the two though.

Maybe this will help.

Thanks for the info, I think I'll stick with the Radeon HD 2600 Pro version on the count that it has more on-board memory and better ratings according to those charts than the 2400 XT. Plus, it comes with a nice 2.4 GHz Intel C2D. Might as well spend a little extra to get more life out of it.
