The 2500K runs at 3.3K stock and the 3570 runs at 3.4K stock if I'm reading the specs right.
Didn't know about the USB, thanks. My understanding was the Sabertooth supported usb 3.0 You also need the chip to have native support to make it happen?
He is comparing the 2500K and 3570K
The K moniker means the CPU has an unlocked multiplier to allow for overclocking. Stock vs stock the 3570k is faster than the 2500k. With an unlocked multiplier you can get better performance by overclocking if you so desire. Also, the 3570k may have a higher GHZ rating, but the architecture is also faster giving it faster cycles per clock. Meaning both at 3.4GHZ the 3570K will be faster.
He wasn't talking about USB3, rather PCI-E 3.0 which is the bus your graphics card uses to communicate with the rest of the computer. PCI-E 3.0 is a technology built in to the newer Ivy Bridge (3570/3770 ect) CPU's which the older Sandy Bridge (2500k/2600k ect) CPU's don't have. It isn't a necessity right now but it might be in a few years coming. USB3 comes with all P67a, Z68, and Z77 boards and does not require any extra special technology from the CPU.
