    GeForce 840M vs GeForce GTX 950M

    When comparing GeForce 840M and GeForce GTX 950M, we look primarily at benchmarks and game tests. But it is not only about the numbers. Often you can find third-party models with higher clock speeds, better cooling, or a customizable RGB lighting. Not all of them will have all the features you need. Another thing to consider is the port selection. Most graphics cards have at least one DisplayPort and HDMI interface, but some monitors require DVI. Before you buy, check the TDP of the graphics card - this characteristic will help you estimate the consumption of the graphics card. You may even have to upgrade your PSU to meet its requirements. An important factor when choosing between GeForce 840M and GeForce GTX 950M is the price. Does the additional cost justify the performance hit? Our comparison should help you make the right decision.
