well my little brother just brought a 5850 and guess what he did ask me for any advice. and he is left with a horrible bottle neck he has an old e6400 so i said i will oc it for him it turns out that the mother board he has, has an fsb wall of 343 (meaning an oc of 2.74ghz which does help but still has a bottle neck) and as you would expect being just a 14 year old kid he cannot afford a new mobo + cpu. so i was thinking as a birthday present i could buy him an e7600 off of ebay for about £40-50 and oc it to about 3.6-3.8ghz (he has a corsair a50 so cooling isnt a problem) will it be worth it and will it solve his bottlenecking ?
(just don't mention overclocking the 7600 lol
