Not as impressive as I thought it was going to be but as said it's not a bad motherboard. Z68, apart from the addition of SSD caching doesn't really seem worth it tbh, I know some of the boards offer the use of the IGP but if you are spending over £150+ on a motherboard it seems a waste to use the IGP and not a proper GPU.
With the IGP you also get the Lucid chip (on some boards) and the ability to overclock the CPU where as on H67 you only get use of the IGP which can be overclocked but no CPU overclocking and P67 no use of the IGP and only CPU overclocking.
Combining the use of the IGP and being able to overclock both IGP and CPU is good, but again if you are spending money on a decent motherboard i'd say it's best to go with P67 with a proper GPU or a high end Z68 motherboard with a proper GPU. The SSD caching is good but i would like to see the tech mature a bit to see what it is fully capable of on future motherboards.
Good review anyway Bryan
