Line of thinking:

Since UXGA 15" screens are no longer available for T60P therefore not available for core 2 duo...which is a shame...

so> choices:

1. Buying a 15 inch T60 which has core2D already, have screen replaced later with a UXGA 15 inch.

2. Buy a UXGA 15 inch T60 core duo from third-parties that still got them and later upgrade the CPU...

What line would you choose?

The first option, as we do not know whether the current core duo boards have the new power VRM yet or not, and hence an upgrade to c2d is unsure.

Unless you need the 64-bit, don't worry about C2D -- performance difference will hardly be noticable.

The performance jump from CD to C2D is actually quite substantial.

Reviews show up to 20% increase -- hardly substantial. Core Dual, Core 2 Dual on the 65 nm fab. Next substantial increase with 45 nm fab in 1 to 1.5 years.

I dont know what you do with your computer, but a 20% increase in performance is rather substantial to me.

I have read the anandtech reviews about core2duo. and the performance gain is not too noticeable..BUT the adressability of more than 3gb ram is important, and that is the aim in the long run....

The days of 100% and 200% increases in speed are pretty much gone. These days, a 20% increase is huge, and people still get excited over increases of 5% through overclocking and whatnot.

Actually, for many applications (and some yet to be reprogrammed in the future), current change to the Core Duo with two processors and the change to 65 nm from 90 nm technology provided such substantial peformance jump. For instance, Excel 2007 is rewritten for multi-threading such that you'll see a substantial gain in performance. You can download it now if you like and try it. Many other CPU intensive applications have yet to be rewritten for multi-CPU environments but assuredly will be in the future (as in Excel 2007) given the changeover to all future CPUs both desktop and laptop going to multiple cores.

20% increase is nothing to write home about and just isn't worth the cost and time and trouble of a CPU upgrade. Of course, if you don't want the UGXA which isn't avail in the next generation, then by all means go with the C2D.

As long as you run 64 bit os

Indeed, performance jumps like that are nice, but right now we're just discussing the performance jump with a certain software set on C1D and the same software set on C2D. Rewritten software isn't really relevant to the topic of hardware performance boosts.

But I look forward to using said rewritten software on Core 1/2 Duo.
