Looks from benchmarks i will tell you the truth ! Also its going to be short :)
Its better then the 2500K. The 8350 is for the people that has the AMD3+ boards ... purchased due to the hype. IF you dont have a AM3+ board then forget purchasing this chip, go intel.
The 8350 isnt better then the 3750K, in the UK 3750k is £5 more then the 8350.
8350 ISNT a bad chip, but lets be serious the 3750K is better in most cases. The 8350 has 8 cores ( to the noobs, more cores does not mean better chip ) so in multi treaded application it has a really good advantage. The 8350 in my eyes in more to do with video edititors,encoders,multi taskering and gaming. The 3750K is for the hardcore gamers that are trying to get the best FPS, but im going to be honest if your such a hard core gamer just upgrade your gpu ( if your playing 120 fps and you drop by 7 fps, you wont be to tell. )... im making things to long and i cant be arsed to type no more. 3570 vs 8350 = draw
