When considering an upgrade from the Radeon 6900 XT to the 9070 XT, it’s helpful to weigh the costs against the potential performance gains. Currently, the 6900 XT can be sold for approximately £380 on eBay, while a new Sapphire Pulse Gaming 9070 XT is priced at £558. This results in a net upgrade cost of around £178. Whether this investment is worthwhile depends on the performance improvements offered by the 9070 XT and how much value you place on those enhancements for your specific use case.
