Am i doing everything right? Will all these parts function well together? Is there some gaping discrepency? Thank you all.


any suggestions on the RAM? also if i was to overclock the processor, should I buy an aftermarket CPU cooler or is the stock cooler typically sufficient?

and would it be wise to purchase anything in addition to this setup? i.e. extra case fans
THANKS
