Hello everyone. I'm looking to upgrade my roughly 6-year-old gaming pc with a new graphics card. I'm looking at something in the range of the rtx 4060 or 4060 ti even though the reviews for those haven't been great. Looking to stay in the $400 price range. My other concern is bottlenecking if I buy too much graphics card. Is it worth upgrading just the card or do I need a whole new rig? I currently play at 1080P but would like to get something to game at 1440P in the near future. Here are the specs of what I currently have in my pc. Let me know your recommendations for what I should do. Thanks!
