My old computer was a 32bit one, my new one is 64bit with a 64bit version of Windows 7 installed. The worst thing about setting up a new computer is trying to get your new one set up to act, look and feel just like the old one. It has Windows 7 Home Premium (圆4) Service Pack 1 (build 7601), 1.65 gigahertz AMD E-450 APU with Radeon HD Graphics, Multi-core (2 total). So for about $380 I purchased an Acer Aspire X1430, a desktop model.
Usually I would fix up an older one lying around but instead decided to go out and buy a new one. My main computer since Dec 2010 conked out on me recently.
