FUD Zilla claims NVIDIA will try to address AMD's Cayman by introducing a GeForce GTX 580 card in November. The site claims the cards are in production right now and that pricing is expected to be around $499, but that this will depend a lot on the performance and pricing of Cayman.
We came across some interesting information regarding Nvidia's response to Cayman. The new chip from Nvidia, codenamed GF110 is going to launch in November, most likely before Cayman. AMD set its launch date around November 20 and Nvidia is likely to launch the GF110 a bit earlier.
It is not only that the chip will have more than 480 cores, we dare not say 512, but all these cores will be improved. Nvidia had more than a year to work on this mid-life kicker, something that can compete with AMD's Cayman and could likely end up as the fastest GPU on the market.
