I've already ordered the 840 EVO online for 159$ and did not notice the new 850 EVO, so after looking for a solution, I tried to cancel my order but it was too late. So I'm now considering returning the 840 SSD and get my money back, so I can buy the 850 EVO for 133$ (I would save 20$), but after looking at the return policy, I will still have to pay the restocking fee and also the shipping (about 30$ at least). So my question, does it worth it to do that ? or the 840 is just enough and there is actually no big difference in performance ?
