1) you are again doing the mistake of comparing R5 with i7 (15k vs. 23k plus cooler). R5 2600 should be compared with i5 CPUs
2) In your budget you need a gpu just to get display. There is no question of bottleneck if you're using it to get display. Rest assured even your old gfx card is enough for that. Intel has an advantage of using their IGPU for performance in some apps.
3) I am not aware of any mobo that has ps2 ports. They were replaced by USB ports long ago. And it's for the better imo. Is there a specific reason why you need them? I'll also see if I'm wrong here.
