Hi @Yessir! With your revised budget, I'll say it's definitely a little more comfortable in terms of putting a build together. One thing I do want to mention though is that monitors with G-Sync built in tend to be more expensive so I think it'd be better to stick with a cheaper monitor and keep most of your budget for the parts in your system. With that in mind I came up with this:https://www.microcenter.com/site/content/custom-pc-builder.aspx?load=811f05dd-f512-40dc-9151-191fb9a7f8d2It's just over the budget listed at $1013.89, but that is before taxes so if you need to take down the price a bit I would recommend you go down to a GTX 1650 Super instead of the 1660 Super. With a Ryzen 5 2600X for your CPU and 16GB of RAM on this build, it's a comfy budget option for entry level streaming. You won't be able to stream at very high settings, but it should be good enough to get the job done. With that said...You could also buy the Powerspec G162 instead, then put in an extra hard drive for storage space and buy a 24" monitor. With the HDD and monitor added it would actually be right about $1000 after taxes but you'd get an upgrade on your processor with the Ryzen 7 2700X which would handle streaming very well.
If that's within your budget, I think it's a good build overall. Personally I would go with Ryzen 5 3600X and upgrade your GPU to something like a 1660 Super instead, but I think you'd be happy either way.
