A:AnswerYes this comes with a stock AMD cooler and preapplied thermal paste. It is sufficient for normal operation. If you intend to overclock consider liquid cooling. If you need a compact cooler for an ITX case, consider a low profile CPU cooler like the Noctua NH-L9a. Either will come with preapplied thermal paste as well.
A:AnswerShort answer: No
Long answer: The 5700g requires a motherboard with an AM4 socket. I currently use the MSI MAG b550 Tomahawk WIFI with the 5700g. You can find cheaper AM4 motherboards, however, this one has all of the features I needed and is usually in stock at your local Best Buy.
A:AnswerNot sure about the cache in this chip. This chip has integrated graphics and does not support gen 4 picie lanes. You would be better off using the 5800x3D chip that does have 96mb of L3 cache.
A:AnswerLook online for the specifications of your exact pc model. Many prebuilds are not very upgradable. The answer would be specific to what model & parts you have. This processor is compatible with only certain motherboards. Parts availability is another issue when considering to upgrade, so best to do your search. try pcpartpicker.com for compatibility.
