Bjorn3D has previously reviewed the performance difference of the stock 9800GTX versus various high-end and mainstream graphic cards: namely the 8 series cards (review). We are fortunate to receive the Foxconn GeForce 9800 GTX Extreme OC card which features clock speed of 780/1900/2360 (core/shader/memory) as opposed to the reference speed of 675/1688/2200. Today, we will put this card against other mid-range graphic cards ranging from the last generation G80 to current generation G92 cards and even the HD card from AMD.
