Dell Small Business offers the Dell OptiPlex 790 Intel Core i5 Quad-Core 3.1GHz Desktop PC
(no monitor) for $619
with free shipping
. That's $426 off and tied with last week's mention of this model as one of the best prices we've seen for a Core i5-equipped OptiPlex with Windows 7 Pro. (For further comparison we saw an OptiPlex 790 with a Core i7 processor but less RAM for $3 more in May, since expired.) Sales tax is added where applicable. Features include an Intel Core i5-2400 3.1GHz "Sandy Bridge" quad-core processor, 4GB RAM, 250GB 7200 rpm hard drive, DVD burner, and Windows 7 Professional 64-bit.
