I have read good reviews from the different sites about the Cooler Master Hyper 212 plus. I might buy it instead of the Consair H50. I have the Consair HX850 psu in mind. Do you think it is overkill for my system? I build this new computer for video editing and casual gaming.
Actually, I would go with the Cooler Master Hyper 212+ & air cooling. I don't think the H50 is worth it compared to the "higher level" air coolers. The Hyper can pretty much match the cooling of the H50 at 1/2 the cost. You compare the H50 to the $70 air coolers and it loses.
To get the true benefit of water cooing, you need to buy components for it... Not a All-n-One setup. The cost is more around the $200's or higher. Performance of those setups are hard to bet in cooling.
