Question Replacing CPU and VRAM

[madican]

Need a help with advice. Currently i have i7 4790, 16GB vram. Tomorrow i will change them to another components, first CPU today i got used 4790K version and Vram later with 32GB. Motherboard is z97, windows 10 pro latest all updated. So if i change both of them at same time, will after that my PC normally starts on? About used CPU, i wanted to buy a newest but in my country it stopped selling.... 3rd party Seller told me that this CPU works well, he is tested. I hope it's ok....
