Which of the following is better for Lightroom/PS usage?

As you all can see, the main difference is the CPU used. I know that Xeon E3 V3 is a great CPU with an amazing performance equivalent to i7. If I choose the more expensive E3 then I will be compromising on other aspects, for instance, monitor. Vice versa, I can have more ram, better SSD, etc if I choose the less expensive i5-6500. (I don't do any gaming so don't blame me if you see Sapphire Radeon HD 6450 on the list XD.)

I am not a professional photographer, and my raw files are mostly 16 MPs. Performance-wise, I know E3 will out-perform i5 but I don't know if there will be a very noticeable difference when it comes to using Lightroom 6/PS CC. Benchmarks are useful, but sometimes do not really reflect what we will need in the real world, right?

Also, I am just concerned that whether entering Skylake platform with i5 6500 will be a smart move, since E3 V3 is relatively old in terms of architecture and I guess may not be so good a choice at this point in time in 2016, especially considering my PC will be built in August.

This will be my first build, so these questions may sound very stupid to a lot of you. Any comments are welcome, and I do hope anyone who have used i5-6500 on Lightroom/PS could kindly gimme some real-world feedback on this CPU. Of course, if anyone who could come up with a better list at this price range, that will be greatly appreciated!

Thank you!
