the RAM timing is not so important for gamers , but you MUST use 1.5 volt RAM .
I would spend less on the motherboard . A high end board with features you dont want to use is just wasted money . It wont perform better than a board costing $50 less that uses the same Z68 chipset
Also since you are using an ATX case , why use a m-ATX motherboard?
