If this is for gaming as your build title suggests, at less than half the cost, this will give you mostly similar or better performance...

The cost isn't an issue. It's for both gaming/work/livestreaming but the only issue I have is if the graphic card will fit in the case I chose along with the cpu cooler.

The card will have enough clearance as per the specs. Not so sure about the cooler though, but from the look of it seems fine to me.

Thanks for that, also thank you for taking the time to do that other build you recommended (thought I came off as rude from my comment so I apologize for that) I will most likely use it as a streaming PC if/when my content creating career kicks off!
