I purchased an XPS 420 desktop system w quad core 6600, 8 gig, 500 gig sata, 8800gts, vista 32(upgraded to vista 64 because the oem license is either and MS has media for it ), 24 widescreen monitor and a g11 keyboard for just over $1600.

I manage several 100 dell desktops/laptops across the country. We have several machine still in live enviroments that are over 8 years old. The only problem was we had (and everyone else had) was with the sx260/270 usff desktops machines and bad capacitors on the MB for short time. Luckily dell extended the warrenty on those machines. Other than that, I would recommmend Dell to anyone.
