Question Can I upgrade or do I need to start a new build?

[Morrow28]

I am getting back into pc gaming and am wondering if I can upgrade my old pc, or if I need to start from scratch? If I need to build a new pc, do I have anything I can salvage from my old pc? This is what I currently have:

ASUS Essentio CM6730-US005S - tower - Core i5 3350P 3.1 GHz - 6 GB - 1 TB Specs

My budget is very limited, so I'll be upgrading as I go, or if I need to start a new build, I'll likely be buying as I go. Given that, where would be the best place to start?

I live in the US, I'll be using the pc for various games (wow, minecraft, indies, skyrim, etc) and for streaming (though this is the less important of the 2). If you need any other info I'll be happy to provide it.

Thank you!

and how limited?

and how limited?

Like $100-$200 a month. So if it's an upgrade situation then I'll probably buy a part a month. If it's a fresh build, then I'll either save up and buy all at once or buy the things not likely to get outdated first.
