I didn't understand much from the comparison page. Just tell me if UD5H worths the extra cash.
I have 8GB of 1600 ram, gtx 560 ti, 850w psu and i7 2600k. So which one should I pick?
I would suggest the UD5H option for the better audio performance. The other little things are nice as well in my view but if the price differential isn't significant for you then a little extra for better audio is worthwhile. But, if that doesn't matter to you, save the money and apply it elsewhere or pocket it.
