extra cache may make a big difference in games if you run at low gfx settings so you're getting hundreds of fps (
eg.. ), but benchmarking game performance like that is misleading, you just turn the 'game benchmark' into a spi clone (10-20% performance difference due to cache alone). at realworld settings the difference between a q7500 and q9450 set to equal fsb & multi would be more like 1-2% (except for high end multi-gpu setups)
eg vaguely like the top 3 graphs on this page
