Both are stronger for both gaming, and work [rendering] than Your initial call.

miningshark23 - logainofhades has a good point with his build. Better chosen components, and You can have the "allmighty" GTX 970. Except the storage, which is a disaster, but You can upgrade to SSD later. And a motherboard, on which You cannot overclock in the future, also isn't the best step, but if You don't plan on overclocking, it's a good choice.
