You don't NEED 5Ghz... Anything over 4Ghz is plenty for today's gaming unless your running quad GPU's
Like they say mate it is a bit of a lottery dip.
I agree with you although you dont need 4GHz+ the extra really ramps up framerate with dual cards is all I know.
Degradation VS bang for buck .....the 2500k is so cheap, I would feel sick I brought a extreme. hehe
I run ONLY 4.5GHz max 24/7 ........ but it is nice to gloat ! . lol jkhttp://img43.imageshack.us/img43/8894/5ghzm.th.jpg

On the upside the next owner in 9-12 months most likely will be happy to know he has a chip did 5GHz easy
