Everyone of the prebuilts on Bestbuy fails to mention the model of psu, board, etc .. and I looked at almost all of them just now. I also noticed most of the cases used for them have horrible front ventilation/airflow. Unless you have a line of credit at Bestbuy I'd order the parts and build it myself or take the parts to a local PC shop and pay them to build it for you. You can also order the parts from Bestbuy and have them or a local shop build it. Check Amazon and Ebay for
new gpu's such as an RTX 3060, 3060 Ti or 3070. 550w psu for an RTX 3060 and 650w psu for a 3060 Ti and 3070.

Review of that cpu w/benchmarks
https://www.guru3d.com/articles-pages/intel-core-i5-11400f-processor-review,1.html
The Core i5-11400F is Intel's most affordable Rocket Lake processor. While its multiplier is locked, you can still adjust the power limit. Once we did that, the CPU ran over 15% faster and almost matched the Core i5-11600K. We also made an interesting discovery regarding Gear 1 vs. Gear 2.
