Its really your choice, I advise 1080p for gaming as when playing games 1440p doesn't really make much of a difference and the framerate dose but watching videos or looking at plain text or pictures the resolution will probably be more useful.
At 95hz unless your an esports highly competitive gamer the difference between 95hz and 144hz you will likely not see much of a difference. Although I advise 144hz over 1440p the minor differences get very expensive.
I've seen a system very similar to this built for a budget gaming pc and it performed fairly well I've changed the motherboard and the ram but I'm not sure how you're meant to get a better upgrade for the cpu as games only really utilize around 4 cores and from the benchmarks I have seen online...
It all seems fairly balanced to me. I could spend more on a better cpu but the thing is I could spend more on a graphics card I just want to know, am I going to run into any bottlenecks or something like that? Or is there a upgrade that would largely greaten my performance for not too much money?
That seems like 50% more budget for not 50% more performance couldn't I just use these specs and be good? As spending $270 on a sdd a slightly better motherboard and a slightly higher clock speed cpu seems like a waste:
