Reports regarding the most minute attributes of Nvidia's upcoming GeForce 8800 GT graphics cards have been appearing on rumor sites by the truckload lately. Based on those reports, we know 8800 GTs have a single-slot cooler, a 65nm graphics processor dubbed G92, and that they're expected to launch on October 29 in the $199-249 range.
The latest news is that early 8800 GT cards may be suffering from overheating problems. A new report by The Inquirer says Nvidia sent an "urgent letter" to PC vendors asking them to send in systems for "thermal analysis." The Inq says it heard the same story from several PC vendors, who added that Nvidia gave them roughly a week to comply without providing any further explanations. Since the G92 GPU is expected to be smaller than the G80 found in current GeForce 8800-series cards, The Inq speculates that the culprit is the 8800 GT's cooler, which may not be performing adequately on production hardware.
In related news, Fudzilla has word that Nvidia will retire the GeForce 8800 GTS 320MB once the 8800 GTs launch. The 8800 GTS 320MB should be replaced by an 8800 GT with 512MB of memory, the site says.
