I just bought my new PC

Try to get as much ram as you can afford at least 16 or 32gb especially for 64bit systems, much more reliable when you are multi tasking with more than 1 application. You will need more hhd space too over time. Also ensure you have good power supply unit.

Congratulation! New PC is my next dream...

If you, change the graphics card (and add another one if you can afford it). I use 2 x 1080ti's in my main PC, it really does make a massive difference. I have a 1060ti in the other one and it is a lot slower. Good stuff, either way, at least you will be able to kick out some nice models with your set up!

As salex said though, bang in as much memory as your pocket will allow.

It's very good PC! Though, I would recommend that you later add at least another 8gb of ram if you want some serious modeling. 8gb with windows 10 is ,rather small in today's standards! Good luck with your machine. I hope it will serve you well and for a long time! Cheers

Congratulations. It looks like a pretty decent machine! The Ryzen 5 2600 and GTX 1660 are both solid hardware and being a desktop you could always upgrade all parts down the road. It should be really good for gaming. My only concern is the 500GB SSD and 8 GB ram. Will those be enough for doing the work you do? I personally found a big difference in reliability with some applications when I went from 8 to 16 GB ram, and then again to 32. Fewer crashes, less lag. I've also found 500 GB cab get filled up quite fast (at least for me), especially when it's the only drive for both software and storage. I'd probably invest in a large format HDD just for archiving and backups.

Good luck with it! I'm sure you'll be quite happy.
