ok been looking at the next cpu to get, my choices are?

[Intel Core 2 Duo E4500 2.20GHz Socket 775 800FSB 2MB Cache Retail Boxed Processor

or

Intel Core 2 Duo E6320 (1.86Ghz) Socket 775 FSB1066 4MB Cache Retail Boxed Processor

which one would be the best option to go for? how does the cache affect it?

this is going to be a games aimed machine, so the caching im guessing it not a high neccessaty
