My son runs a g860 on a basic Gigabyte H61 board with a GTX460. Now without a stopwatch in his brain will he see any discernible difference using a Z77 based board? May I add I run a 2550k on a Z77X-D3H but surely it's horses for courses. I believe no conventional hard drive achieves sata 2 speeds let alone sata 3 for instance but many forums say sata 3 is a must have and so on. All too often enthusiasts seem devoted to expensive overkill.
