Really? 4,5GHz not enough for SB daily use? I think it's awesome news so far.
I'd be really happy with a 4.5GHz STABLE oc (key word being stable) on a 2600K with a mitx motherboard. I'm sure when the board is released we'll be hearing about 5GHz+ OC's but will they be truly stable? I see alot of SB cpu's on these forums at 5GHz+ on air and I have to wonder if they're truly stable at that speed.
In my limited experience with a 2600K and asus P8P67 I was linx and prime stable at 4.8GHz but x264 would cause the system to lock up after a while. I had to dial it back to 4.5GHz to be truly stable.
