which models do you think are more reliable though?
Wouldn't a 2.0 with 128mb vram be a revB and a 2.0 with 256mb vram be a revA
If so, would it be better to get the revB??
What about the Core2 Duos....do you think those are even more reliable?
The graphics card in the C2Ds is clocked higher than in the previous generation which indicates to me that they're managing the heat better. So it looks like Apple did make some under-the-hood adjustments to improve the performance and, presumably, reliability.
With the 2.16ghz C2D ($1599), you also get a faster superdrive, firewire 800, and larger HD. You do get a 256 mb graphics card in the CD machine ($1549), BUT as I mentioned above, the 128 mb card in the C2D is clocker higher.
Also note that the C2D MBPs are considerably faster in Photoshop and Aperture. This probably has something to do with the larger cache of the C2Ds. If you do a lot of image manipulation, the C2D is the way to go. For benchmarks, see Barefeats:
