[strike]For starters, you won't get the G3258 to 4.5Ghz on a stock cooler[/strike] Secondly, you won't be able to use that motherboard to overclock as it doesn't have any heatsinks. So the short answer is
no
Edit: Just Googled G3258 4.5Ghz overclock and it appears you can overclock it to 4.5Ghz on stock cooler, apologies. I would still recommend a motherboard with heatsinks, though.
