Dell sends me a add every once and awhile and in it was a quad computer for under $500. I had bought one a year ago for around $600. The one I bought was a q6600 vs q8200, 2 gigabytes of memory vs 4 gigabytes, 500 gigabytes hard drive vs 750 gigabytes hard drive, 32 bit vista vs 64 bit vista. Everything is better and cheaper. I looked up the cost of the q8200 microprocessor and found that it alone would cost me over $160 so even upgrading the microprocessor alone seems foolish with the price they want for the new computer as I would still have an older and less capable hard drive, operating system, and memory. I guess if I wait another year maybe they will be selling the octal computer for less than I paid for the quad and with two threads on each processor I could use one computer to replace the four I have now as I did use the 4 I have now to replace the 7 I once had.
