Flour of choice: system unit or video card?

Question

Iron

Hello, I got some money (free) and decided to make a gift for NG, myself, my beloved. Tell me please, I'm tormented directly, because there is enough either for a video card or for a system unit ... The configuration right now is this: i5 3470, 16 Gb Ram, GTX 970, p8 z77 v-lx. So I think: buy a vidyahu, and then a system unit or a system unit, and then a vidyakha. Of course, I want to buy everything new, bicosis guarantee, etc.. It’s stupidly not enough for everything together .. And yes, no, no, I play, despite my advanced age))
I read all sorts of crap, they say, buying something for my processor like GTX 1070 - just a waste of money (I almost bought it the other day) and now I don't know ..

Answer 1

Well, everything is simple: the higher the resolution, the more important the video card. That is, for 1440P and 4K, it makes sense to fork out for a video card, because the processor will change almost nothing. You have FHD, and not the worst graphics card, so I think it makes sense to replace everything else. However, you will not see miracles in games after such an upgrade.
The processor mainly affects 5% low to a greater extent, and avg fps to a lesser extent - that is, with an old processor, your fps will simply be lower than with a new one, especially its lower limit.

Answer 2

GTX970 ~= GTX1060 6Gb. Therefore, I think it is advisable to invest in the rest.
