Dell now has this powerhouse Dimension E521 for $589 (I mentioned it last week as a good deal at $644!). It has the new AMD Athlon X2 Dual-Core processor, 1gb memory, 160gb hard drive, 16x DVD / CD burner, 256mb video card and a 17" LCD flat-panel monitor (it is $679 if you upgrade to a 19" UltraSharp LCD and $809 if you upgrade to a 20" Widescreen UltraSharp LCD). This is the best desktop deal I've seen in some time. The price should be valid through 6am CST 11/2. Shipping is free.
