I recently made a website to help with comparing processors and graphics cards. The way that this is different from existing comparison websites is that you can apply more filters and view performance to price ratios. The URL is here:
For the ones that are available on Newegg, they should be updated daily. Obsolete processors and graphics cards only get updated if they're available on Pricewatch (and the old ones are usually refurbished or used so the pricing data for those is a bit skewed sometimes).
Yeah, Futuremark's being a bit slow on the new ATI cards. It should improve after a week or two.
Also, if you feel that the processors with the highest perf/price ratio are relatively horsepower-light, you can check "performance takes priority over price" and it will put them higher in the list. Or, just enter a higher minimum rating.
