Perhaps a great new video card can "mask" things. Quite frankly, if a brand new Bulldozer 8150 at 3.6 Ghz, some form of Turbo boost and 8 cores doesn't smoke a SB 2500k little lone a 2600k, AMD will quite frankly look silly. I say this because the 2500k/2600k chips have been out for almost a year, both "only" have 4 cores with the 2600k having hyperthreading to 8 cores, they only run at 95W while the Bulldozer runs at 125 or 130W. Geez Louise. Based on the raw power differential the Bulldozer should smoke them. If it's nearly a draw with a 2500k at stock(they overclock like wild) and Bulldozer doesn't scale as well overclocking, things will be gloomy in AMD ville.
I have always been AMD since the 386DX40 came out until now. Time will tell.
