Pny Xlr8 8800 Gtx Oc
 

The PNY XLR8 8800 GTX OC has a list price of $579.99 and it is one of the more affordable factory overclocked 8800 GTXs currently available. The XL8 has its core, shader, and memory clock frequencies all overclocked at the factory so it's ready to rumble right out of the box. It receives a 100MHz (200MHz effective) memory overclock, 108MHz shader overclock and a nice 46MHz overclock to its core. While 46MHz doesn't seem like a whole lot, consider that it makes the XLR8 9MHz faster than a stock 8800 Ultra.
