Yes, you can get better performance by replacing your graphics card. The exact amount of performance improvement will depend on the type of graphics card you have currently and the type you are replacing it with.
Generally speaking, if you are replacing an older graphics card (such as one from a few years ago) with a brand new one, you should expect to experience at least a modest boost in performance. This is because newer graphics cards generally include more powerful processors, higher clock speeds, and more memory than their predecessors. Additionally, some of the newer features available on modern-day graphics cards, such as ray tracing, may provide additional performance benefits.
In terms of specific numbers, how much performance you can expect to gain by upgrading your graphics card will depend largely upon the specific models involved. Generally speaking, however, you should expect to see at least a 10-20% improvement in performance when you upgrade a midrange or budget graphics card to a high-end version. Some enthusiasts may even report performance gains of up to 50% or more, while others may experience only minor differences.
The amount of improvement you experience will also depend on how well optimized your games are for the type of hardware you will be using after upgrading your graphics card. If you’re playing a fairly new game that is already well optimized for the current generation of graphics cards, you may not experience nearly as much of a performance improvement as you would when playing an older game that isn’t designed for more modern hardware. By contrast, an older game that hasn’t been optimized for modern hardware will likely run more smoothly after you upgrade to a more powerful graphics card.
Finally, the amount of performance improvement you get from upgrading your graphics card will also depend on the graphics settings you are using. If you are playing games with graphics settings that are already maxed out, you may not experience much improvement in performance unless you were to lower the settings or switch to higher-resolution textures. On the other hand, if you are playing with settings that are below the recommended levels for your graphics card, upgrading to a more powerful model can yield much more significant performance improvements.
In conclusion, upgrading your graphics card can provide significant performance improvements depending on the specific models involved and other factors such as the age of the game and the graphics settings you are using. Generally speaking, you should expect to see at least a 10-20% improvement in performance with an upgrade, though some enthusiasts may report larger gains of up to 50% or more.
