Hello,

I have been thinking about upgrading my 4~ years old PC because its really laggy but i don't really have the money to do it, i have seen some really cheap parts and i wanted to buy them but firstly i want to ask the community which knows better than i do (i have never upgraded a PC or build one)

So my question is, can i upgrade partly ? and by that i mean, upgrade a CPU, turn it on Test for a bit, then if i get the money for GPU i get a new GPU and turn it on Test it etc.

(I put it in CPU category becouse this is what i want to upgrade first & i don't know where else)
It might be a really easy question but i really want to make sure that i can do that

Thank You for reading!

(I know its really bad)

Many people told me to start of fresh but i haven't really got money at the time and if i just do this partly then i can do this the way that is more comfortable to me and better for me too but im not the... good one here becouse im really bad at upgrading/building pc
 
Oh yeah i forgot about line ups, so i unfortunetly need to start of new, but could you still help me which are the best/pretty good parts that i can build that aren't that expensive ? im really bad at that type of stuff.
 
When you upgrade the CPU you are basicly doing a platform upgrade. Since you have to change the motherboard as well and most likely the RAM. So if you are changing the CPU its most likely the CPU + Motherboard + RAM, and perhaps Windows. If you are looking to add just a GPU you can keep the rest the same. If you are upgrading your boot drive you may need to reinstall Windows, but since the motherboard is the same you should be able to use the same copy of Windows.

I'm looking to upgrade and I'm going to probably go CPU-Motherboard-RAM as my 1st and a GPU later if I feel it is worth it. Of course I may have to get a new version of Windows too. I'm waiting to see what the Zen 2 3000 series has to offer I may go that route. I'm not tied to any one brand I'll go with what I feel is the best deal when I'm upgrading. And I have no problem upgrading one component at a time and slowly upgrading my rig over time.
