True.. the main idea of the spec (same with most of my specs) is that it stays next to silent so I specced the very good value 5000+ black edition (which is a brisbane core making it 65nm) and the scythe ninja to keep things very quiet I have the same chip and HSF and it stays pretty much at ambient tempretures.
Since the 780G chipset has essentially got an ATi HD3450pro shrunk into it you don't need a lot of cpu power but the black edition will hold it's value better and overclock with ease due to the unlocked multiplier. This also means the motherboard isn't stressed when overclocking
