??? For a price difference of about £20 ? Oh please.
i5 2500k is the best bang for the buck quad core period.
graniteman, i plead to you, get the i5 2500k.
the i5 2500k for about £20 more will give you overly
significant more performance than the 955.
i'm not disrespecting the 955, 965, 975 or any of the phenom ii series, heck, even the hexacores!
in gaming, the faster your cpu can dispatch information, the very better. in alot of games when paired even a half decent gpu, if the gpu is getting all the information out just fine, but your cpu is struggling to keep up, you will experience bottlenecking. your game may begin to stutter, then matters get worse when your cpu begins to heat up , decreasing performance levels even lower.
When working with photos, the faster your cpu the better. You want to be able to have a boost in speed.. The i5 2500k is faster clock for clock already. They can overclock to 4.5Ghz STOCK COOLING! 5Ghz on better air coolers...
Technically the 955 will do "fine", yet not as good as an i5, and price gap isn't abnormal.
Go for the i5.
