Kris at DailyTech's apparently been lucky enough to get his hands on pre-release 8800GTX & GTS cards. Three things: 1. what's with the odd memory & memory interface sizes? 2. 128 unified shaders?!? & 3. holy crap that's a ton of power they're going to need to run. Make sure you read the linked power article at the bottom.

"NVIDIA’s GeForce 8800GTX will be the flagship product. The core clock will be factory clocked at 575 MHz. All GeForce 8800GTX cards will be equipped with 768MB of GDDR3 memory, to be clocked at 900 MHz. The GeForce 8800GTX will also have a 384-bit memory interface and deliver 86GB/second of memory bandwidth. GeForce 8800GTX graphics cards are equipped with 128 unified shaders clocked at 1350 MHz. The theoretical texture fill-rate is around 38.4 billion pixels per second."
