The news of Sandy Bridge is keeping tech sites busy - but overclocking is not a big feature of those boards, but Intel will still want to keep their customers and fans happy, so maybe the Z68 chipset is going to be the overclockers BFF.
There's a slide making it's way around the internet about the Intel Z68 Express chipset - the slide below lists "performance overclocking" as one of it's features - for the processor, memory and integrated graphics.
Another stand out feature on the slide is "RST SSD Caching" - RST stands for Rapid Storage Technology. This might allow you to use an SSD as a cache drive while using a hard drive as the main storage. This chipset is beginning to get interesting.
Only time will tell!
