I know that a PE is faster than a XT, but my card (as stated above) is doing PE+ speeds. Just wanted to know if there are any additional benefits (apart from the clock speeds) with the PE version (memory timings, other stuff I don't know about..) compared to the XT?
EDIT: My card is a Powercolor X850XT AGP card with an Arctic Silencer on. Idles at 37'c and loads at 57-58'c running the aforementioned speeds.
I have the x850 xt also so did some searching when I got it. I don't have the links but from what I read, your performance gains from a stock to PE flashed are pretty small if both cards are running the same speeds. The flash didn't help anyone gain any more on their core or their memory overclocks, and the sometimes the PE flash slowed things down a small amount because your core and memory couldn't get quite as high.
