Hello,
I would go for the Intel Pentium D 915 Presler 2.8GHz 2 x 2MB L2 Cache LGA 775 Processor - Retail. Reasons higher cache and smaller manufacturing process. looks quite versitile. -------------------- Regards

Yes, definitely the 915, overall better in all areas, including cost

Well, to answer your original question, the nm means the size of the memory chip (nano-meter?)
If you want to know more, search for the differences between high-density and low-density ram. As this is what these different sizes mean. I think the 2x2 is high-density. I don't think they would have any noticeable differences though. I would search google to see what size chip performs better or causes less heat. Realize that I'm not really an expert on this though and am not sure if I'm totally right. Chip sizes and stuff like that can be pretty difficult. |

The manufacturing process (65nm or 90nm) doesn't have anything directly to do with the cache. It refers to the average size of structures on the chip. A processors with smaller part needs less energy to run and so produces less heat. This takes on an added importance with the NetBurst-into-flames architecture, which both processors you linked to refers to.
The 2x2MB and 2x1MB means that the first one has 2MB of cache per core while the second only has 1MB cache per core. Here, more is better. -------------------- "Anyone who cannot form a community with others, or who does not need to because he is self-sufficient [...] is either a beast or a god." Aristotle
