Learning stuff on hardware here and on other sites in order to asseble my first pc (planned to be around 1500€) i've came across a fair number of systems ideas. A thing i can't uderstand is the proper balance between the money you put on the processor and the ones going to the video card (and ram memory to some extent):

the mainstream opinion seems to be that an high-end i5 processor (like 4670k if i got it right) is all I will ever need to play games at 1080p or 1440p, so if i have more than those 200€ to spend i should invest in a better video card instead of taking a more expensive i7 (like the 4770k, 280€ on amazon).

The same goes for RAM, with high-end expert rigs like this:
http://www.tomshardware.co.uk/pc-system-build-value-compared,review-32983.html
mounting 8GB of RAM even on 1600 dollar machines because more than that would bewasted as even games in ultra def don't use 8GB of RAM (from what i've understood).

But then looking to nvidia smartboxes or alienware gaming desktops i see many of theirs machines mount i7 and 16 GB (if not even 32 GB of RAM), sometimes on systems with mid-level graphic cards (like the alienware aurora: 16 GB of ram, i7-4820K, AMD Radeon (TM) R9 270).

even some experts builds from this site seem to like systems with video cards around 300€ and i7 processors, 16 GB of ram instead of saving those 100-150€ to get an higher tier card.

so what am i missing? how do i decide where to allocate the money? are the fastest i7 and 16GB of RAM useful for something below the 4k resolution or it's only a waste of money? will i5 and 8 GB of RAM be a bottleneck under a +/- 500€ card like the nvidia GTX 780 or the radeon axr9 290x ?

(i should mention that i have the specific wish to play planetside 2 at ultra settings, i heared it's particulary heavy on processor but again, so heavy that an i5 can't handle it?)
 
Solution
Depeding on your needs, a quad core like the 4690k could be more than enough for gamng, as many games dont make use of the hyperthreading of a i7.
8 GBs of ram is the least you would want to use in a gaming rig as it gives room for the system to work and the game without being tight on memory usage, 1600Mhz is ok as long as it has a cas of 9 or lower.
The i5 and the 8gbs of ram won't bottleneck neither of those GPUs, but it also depends on the motherboard and PSU you get.

Depends on your needs. I would think that 8GB is enough in my opinion unless you are doing some heavy multitasking. An i7 processor may be used for programs such as AutoCAD and Sony Vegas and Photoshop all running simultaneously. Remember that a GPU is the main factor for gaming though, which is why many multitask and gaming builds have a high end graphics card such as the GTX 770/GTX 780 or the R9 290x/R9 290.
