Need help with this build

Hello @Brrryyannn! Welcome to the Community. 

I would 100% recommend going with the EVGA RTX 2060 KO over the 2060 chosen in that build. For the $60 you save, you don't really lose any performance. That said,  for $360 you could also switch over to an AMD RX 5700 instead which would generally perform better than the normal 2060:

I did notice that you don't have Windows included in the cost of the build, so keep in mind that Windows is another $140. In that case the EVGA 2060 KO may be your best option as it leaves you more room for the cost of Windows. 

The RX 5700 is an AMD card and it's just a little more powerful than the regular 2060 so you'll get better framerates. It's performance is very similar to the 2060 Super, but the RX 5700 costs less so in my opinion it's the better value. 

If you want us to assemble the system for you, labor starts at $149.99 for a Tier 1 build and goes up from there depending on the scope. For the parts you chose it would be either Tier 1 for $149.99, or Tier 2 for $199.99 if you also want us to install and set up Windows for you.
