BTW, I made this thread a sticky.
-Don't buy an X800 Pro or any X800/X850 card....as dhw200 said. They lack SM3.0 and have below par OpenGL performance.
-Also, don't buy Aspire PSU's, get Antec.
-Stay away from KDS CRTs, the picture quality is not the best.
-Don't get the Epson CX4600 or CX6600 All-in-one printer, those are the crappiest printers I have ever seen.
-Don't get Gateway laptops, get Toshiba
-Don't buy any ATI video card with the suffix of "SE", and don't buy any Nvidia card with the suffix of "LE", or without a suffix at all i.e. 6800 (vanilla).
-Most geeks already know this, but stay as far away from Celerons and Semprons as you can.
