We know that Nvidia has those budget 8800 cards coming to us, but now word has it that they're prepping a killer 8950 GX2 card with dual G80 GPUs (clocked at 550MHz) and 512MB of GDDR4 memory for each chip. The card will go for about $600 whereas their other secret card, the 8900GTX, will be clocked at 700MHz and come with 768MB of memory. The 8900GTX will go for $550. By the sounds of it, ATI's got some serious catching up to do if these cards prove to be leggit.
