This site compares every video card for it's technical detail. If you want framerates and stuff you're better off searching for "8400M GS Review" on Google and that will usually pop up a review with benchmarks comparing frame rates of similar cards. Some cards have higher texture fill rates, others have high pixel fill rates. Some have neither but have a ton of stream processors. If you're going to use that site you have to look at every detail. I find it easier just to look up reviews.
