I look at more than a dozen online site from eBay to Tigerdirect.com. Plus I look at the local tech stores for their options. It would be mice to have some printable chart or list showing the order of processing power of the various Intel processors. What I want to buy is 64-bit dual processor type of systems. Many of the current systems out there are sold with 32-bit operating systems running on a 64-bit CPU. My AMD64 laptop from HP was that way. It had 32-bit Win XP/pro. Also the Dual Core T3200 Dell laptop came with 32-bit Vista when it is a 64-bit dual core processor. Most of the systems now out that have 32-bit OSs installed are really 64-bit systems, while some are still 32-bit systems. The companies most of the time do not tell you that their 32-Windows computer is actually a 64-bit system that they did not want to bother with installing the proper 64-bit operating system and all its dt is easier to just install a 32-bit OS and not advertise that the computer can handle a 64-bit version. That is what Dell did on my current default laptop.
If I find a 64-bit system that has only a 32-bit operating system installed, I will most likely install 64-bit Unintu or other flavor of Linux on it instead of using the Windows 32-bit OS. It would be nice to get a 64-bit system that is currently running 64-bit Win7, but those systems usually cost more than the ones that I can afford. I want to replace one P4 desktop [SCSI drive server] and this Dell Inspiron that is always hot to touch without an external fan blowing on the keyboard area. Plus need to do this on a fixed income. Getting the best for the money is a most.
