Insider build

I have a month and a half old Asus ROG Strix GL503-GE i5 8th gen/ 8gb ram/1 TB HDD/256 GB ssd/1050ti I've been using it to play games with a cooling pad and as the processor was getting kinda hot (upto 80-90 degrees) I reduced the power level to processor to 75% in the battery management section...

Which one is preferable for the following specification: Intel i5 7500 G.Skill Ripjaws 8GB 2400mhz WD 1TB Corsair CX450/500 GPU - n/a immediately Are they same in terms of durability for 4-5 years? Suggest please..
