i5 3570K or i5 2500K

I have the 2500k, I'm happy with it for the price/performace..its running at 4.4ghz now and I never have any CPU issues.

If you really want to future proof your rig (or have $$ to waste) then the i7 might be the way to go. On the other hand use the money you saved on cpu to get a better video card and more RAM!

As for Osprey I have no clue what his problems are but without touching anything, I hit the "EASY OVERCLOCK" button on my Asus motherboard and sent the thing to 4ghz out of the box. Once i turned it to manual and tweaked a few settings I hit 4.6 without breaking a sweat.
