[Improving my specs to make game smooth on Ultra]

I'm tracking my CPU usage in arena and it's never above 50%. GPU is not maxed either. Ping is around 120ms. Yet still black screen for 1.5 sec after start of the match. I suppose it's reading speed issue. Would I have to install my OS on the SSD or can I just install BnS and other games on it to enjoy the benefits?

Update: tried what the video says and it maybe helped a tiny bit. Not Much difference. Anyway, I have OC my GPU a bit and it did help. I'm content with the performance. The only thing that bothers me is the delay in arena when the match starts, it loads 1sec later even if I turn down graphics all the way to lowest. Would getting a SSD solve this issue?

Wow, thank you all so much for your help!

I will try doing what the video linked here says and tell you my results.

I kinda got mixed opinions though, I am looking to inprove my specs but now I'm not sure of I should get a better GPU, SSD,CPU or more RAM. I can't get them all ?

What would have the most impact on performance?

What's going on guys? I'd like your opinion on what I can improve on my pc (if at all) in order to run BnS smoother. I run the game on fairly high graphics settings but the fps drops alot in crowded areas or with many mobs, if I set settings to Ultra then fps flactuates between 20 to 60 fps too often so I never set to Ultra.
Another thing that bothers me is everytime I start a 1v1 Arena match, just as the battle starts there's a slight delay (about a second and a half) where I see the START on the screen but my pc hasn't loaded the map yet so I can't actually see anything. This gives my opponents a head start and I can't stop rushes. I wanna know if there's anything I can do about it. 

Here are the specs:
Intelcore i5 2300 CPU 2.8GHZ
8GB RAM
Geforce GTX 1050
Windows 10 64-bits.

 

What do you think? Is there anything I can improve to make the game run smooth on Ultra and load arena matches faster?
Greatly appreciate your help.
Thanks :)
