Hello, I want to buy a new processor but i don't know how to start, or rather what to choose. I picked two suitable processor for my pocket and they are: CPU AMD Athlon 64 3000+ Socket 939 512K bus 2000 0.09u 1.4V 67W 64bit (1800 MHz) and CPU AMD Athlon 64 3200+ Socket 939 512K bus 2000 0.13U 1.5V 89W 64bit (2000 MHZ) The second processor it's cheaper then the first listed.Why? What's the difference between 0.09 and 0.13 microns tehnology? Is the power consumption to high(89W - 67W)? ......Many thanks !!!!!!!
