A lucky bloke who managed to score an engineering sample of AMD's upcoming Radeon HD 7990 sought to make a quick buck by auctioning it on Ebay. An opening bid of $0.99, and 36 bids (ATP) later, the auction has reached the $1,125 mark. The engineering sample is said to ship with clock speeds of 950 MHz core, and 6.00 GHz memory. The dual-GPU graphics cards ships with two fully-loaded AMD "Tahiti" GPUs, with 2048 stream processors each, and a 384-bit memory interface holding 3 GB of GDDR5 memory, each. If anything the Ebay listing gave us some gorgeous pictures of the beast.
