Palit Microsystems is the first Nvidia partner to announce 512MB boards across its entire range of 8600 GTS, GT and 8500 GT boards. The three cards will be known as GeForce 8600GTS Super, GeForce 8600GT Super and GeForce 8500GT Super.
Maybe not the most imaginative model names, but this is pretty typical when it comes to graphics cards. There is no mention of clock speeds in the press release, but the 8600 cards will use GDDR3 while the 8500 based card only gets DDR2.
Both of the 8600 cards also features dual DVI, while the 8500 card gets one DVI and one D-Sub. Apart from the extra amount of memory all of the cards look like reference designs apart from the coolers.
Oddly enough it doesn't look like the products have made an appearance on the official Palit website as yet, but you can still take a look here for more products from Palit.
