kicked things off on Friday by shoving NVIDIA's latest and greatest into its Genesis desktop, and now a few more in the custom PC game have upped the ante by offering a similarly delectable taste of Fermi. NVIDIA's new GeForce GTX 470 and 480 have been all the rage over the weekend, and if those raucous benchmarks have you convinced that the time to buy is now, a trio of system builders are here vying for your attention. Digital Storm's Black|OPS rig can now be ordered with a GTX 480 (starts at $2,891), while CyberPower is giving prospective customers the ability to add the latest Fermi GPUs into a smattering of towers. Maingear's formidable SHIFT supercomputer is also seeing the update, but it's really asking for trouble with a triple GTX 480 configuration that demands a minimum investment of $6,199. In related news, ASUS, Zotac and a slew of other GPU makers are cranking out new boards based on the minty fresh core, so you shouldn't have a difficult time finding one if the rest of your rig is a-okay for now.
