The rumors are now facts. The NVIDIA GeForce GTX 580 is on sale at NewEgg for $559.99 with $7.87 shipping and handling. NewEgg has several models in stock, including graphics cards from Gigabyte, MSI, EVGA, and PNY.
Just to recap the specifications, the NVIDIA GeForce GTX 580 will have all 512 streaming processors enabled, have a 128 texture mapping units (TMUs), have 1.536 GB of GDDR5 memory on a 384-bit bus, is using the GF110 chip, and will have a thermal design power (TDP) of 244 Watts. The GPU clock is running at 772 MHz, the shader clock is running at 1544 MHz, while the memory is running at an effective 4008 MHz. The EVGA card has the core overclocked to 797 MHz, so there is a little headroom left, though I doubt much.
