GeForce 840A vs GeForce GT 545
If you are going to buy a new graphics card and are choosing between GeForce 840A and GeForce GT 545, there are a couple of things to consider. Cards with more VRAM in general perform better and allow you to play on higher graphics settings. Size also makes a difference. A model with a large heatsink can occupy up to three expansion slots on a motherboard. Be sure you have enough room in your PC case. When comparing GPUs with different architectures, more processing cores and even higher TFLOPS will not always translate to better performance. To help you decide which GPU you need, we have measured frame rates in a number of popular games. For more on how the GeForce 840A stacks up against GeForce GT 545, check out specs charts below.
