Ok, sorry I've been off working and I seem to have created a 'nice thread' here. I run CAD/CAM software on my workstation, I remember discussing with the president of the software company about the processors. My computer at home has a 3.2 GHz processor, while my computer at work (which is newer) has a 1.74 GHz processor. My CAD/CAM software supports 64 bit, so in return, I'm using all the power the computer has to offer. Most programs out there do not support 64 bit, only 32 (like my comp @ home) so in return, you're not using the whole computer. So if I'm wrong, I have obviously been mislead, biut then, why were computers listed as 3.2 GHz before, and now (4 years later) only 2.4GHz??? As for the memory, yes you now probably have on-board graphics which takes up some of your RAM. On-board graphics is a little quicker, however you sacrificed it for the RAM...
