This is a nice effort on gamespot's part, but is this really necessary? The benchmarks are just not thorough enough to be very reliable, and if you really wanted a guide like this, a computer hardware site (such as Tom's Hardware guide or several other sites) would be much more useful. I dunno, I think that some of the dollars/frame charts might mislead the people who aren't savey enough to do more research. Better dollar/frame ratio does not mean that its the best deal when you have to worry about future games and cost changes.
