I have really pushed this thing to its limits with high graphics, and its still pushing for a 1660. It is my first gaming PC and have had it for almost two years I believe. I recommend upgrading your RAM right off the bat. most games are hungry of it, COD being one of them. After a COD update, I was getting severe texture loss, upgraded RAM to 32 Corsair Vengeance pro and the unit has been so much smoother running on games. I had issues with temps consistently always peaking and sitting at a solid 78C-80C which is way hotter than I like to see. After experimenting, the front cover on the front of the case if a big blocker of airflow. After removing the front cover, putting dust filters on the front of the fans to help with some of the dust I am peaking at 64C-68C with Very high graphics on GTAV (same as before temps). This is both before and after with overclocked fan speeds (rather replace a fan from over use then GPU/MB/CPU from overheating).Sad to see the market price hike so much. I purchased this unit back when it was only $850 out the door. Good unit for starters for sure.
