Not all Xeon is better than i5 but the Xeon I suggested is same tier with i7 4790 with lower clock speed and no iGPU only.

The difference between Asus and Palit is the price, design, clock speed etc. Asus product is overpriced I would say, you end up paying extra RM 250+/- if you choose Asus for the same GTX970 that you could get with Palit.

With the current technology and hardware offered in the market, it is impossible to run triple A title at 4K at 60 fps (max settings) with just a single card, even the top tier GPU like Titan X.

You might end up with 2 or 3 way SLI of the top tier GPU to achieve that but it is not really worth the money in my opinion.

I will rather wait for 4K ready GPU (with single GPU since SLI sometimes not really working well with some games) before I invest in a 4K monitor or play at 4K resolution at max settings.

But if you want to know how much to spend in order to achieve 60 fps at 4K max settings, you will need at least another GTX980Ti + higher wattage PSU + SLI ready mobo. The total money needed will cost you a bomb 

Even mid end GPU like GTX960 can also support 4K gaming, it is just the matter of playable frame rate TBH 

Medium settings (no AA) probably can have 60 FPS with a single GTX980Ti, if you are talking about max settings then confirmed cannot with the latest triple A titles.
