Wiping

I have had my pc for 2 years now, and i am building a pc with a i7 8700k, asus prime z270 motherboard, corsair vengeance ram, and a 1080ti. i want to know if it is possible to just build the system and just use all of my old drives without wiping them or deleting anything. i dont want to delete...

I am a batman fan..... and i want to play batman arkham knight on my pc ... but my pc is too outdated ...... please tell me if i can play batman arkham knight on my pc.. SPECS : i3 550 @ 3.2ghz nvidia geforce gt 630 8gb ram

I have a Lenovo c560. Changing CPU for G3240T to i5-4570t. The new cpu includes a a new fan, do I need to change it out or should the original be fine? Thanks
