Just comparing a refurb vs new (white) MacBook, is there a noticeable difference in CPU power between the older 2.4GHz on 800MHz bus vs. the new 2.0GHz on 1066MHz bus? I know the newer also has the better video card. They're both listed at the same price, so just looking for best bang for the buck.
Thanks!
In terms of raw speed, they'll both be roughly the same. 2.4 is a faster CPU, and may be better for very CPU intensive apps, but the 800MHz FSB is a bottleneck, and you'll notice the difference immediately if you use USB or anything else FSB heavy at all. I haven't done significant benchmarks, but they both feel pretty snappy in terms of general processing speed.
The real difference is the video chipset, and that is a HUGE jump in the new ones. Even doing simple everyday things like Exposé, you will notice the difference between the Intel and nVidia chipsets. And the difference is only going to get even more noticeable when Snow Leopard comes out which has even more 3D acceleration demands.
I would say, get the new 2.0, no question. For the video chipset alone it is worth it over the old 2.4.
