For at least the next few weeks or months, NVIDIA’s $499 USD MSRP NVIDIA GeForce GTX 580 is the fastest single GPU video card on the planet.
It’s what the GeForce GTX 480 should have been. It runs quick, runs cool and runs quiet. But also it costs $500 and that’s way out of my price range.
Reviews have been positive (check AnandTech’s and Tech Report for their takes), but they all realize that AMD’s Cayman GPUs are around the corner which may grab that crown back in just a few short months.
