We know the RX 7900 XT isn't future-proof, but realistically it's a very capable GPU that will last for around five years from launch - perhaps even longer if you don't need a very powerful system in further years to come. The truth is, with a card such as the RX 7900 XT, you have the power to run most AAA games with ease for 5 years or more. Whether it continues beyond that will depend on support for AI-enabled features, and how far gaming and productivity requirements extend.
