Thinking about this

The 3060Ti is capable of fair to good performance at 1440p, but it seems to me you'd prefer a little better. This proposal makes some major changes, but stays close to budget and allows for a GPU that's 23% stronger for the long haul.

The Lumos case saves $174, essentially paying for the whole GPU upgrade. You will never know the difference between the DDR4 memory and DDR5 for gaming. You really need the nearly double speed of a 980 PRO for your primary drive. The 500GB model isn't a compromise, it's my preference for OS, apps, and maintenance software in an easily manageable package for faster scans and backups. There's a lot of room left for a few of your favorite games. The 2TB 970 is perfect for your extensive games library.

The heart of the matter is a 3070Ti, which will give you performance well over 100fps for a whole slew of games, where the 3060Ti would struggle a bit. I know I changed a lot, but the Lumos is a very attractive case with great airflow. You don't have to have the extra RAM, but it means no worries for the life of this system.

If you're married to the Velox, I still recommend the DDR4, and the storage change. The 3060Ti will hold it's own until someday you want to upgrade, but I think you probably will.
