Approximately two months ago I purchased a Vostro 420 tower to use for my home based business. I got the Dell Vostro 420 with an Intel Core 2 Quad Q9650 (3.0GHz, 12L2Cache, 1333FSB) with 4GB Dual Channel DDR2 SDRAM 800MHz - 4DIMMs and a 1TB Serial ATA Hard Drive. If there were an award for speed for a computer (like there is for cars, 1997 the fastest speed achieved by a vehicle on land. The current record holder is ThrustSSC , which has achieved 763 mph, or bit less than 1228 km/h over one mile, breaking the sound barrier. ) then I think my Dell Vostro 420 might be in the running. *grinnnnnn* My computer technician advised me (as he was setting it up) that it was hands down the fastest computer he had ever had the opportunity to work on. So here I am, two months later with all kinds of extra software downloaded on this baby and it still moves like its on high octane rocket fuel. I highly recommend Dell (I've made the mistake of trying another brand on my previous machine) and will remain a faithful Dell customer for my next ten or twenty or so computers.
