GeForce 840A vs Radeon HD 6850
If you are going to buy a new graphics card and are choosing between GeForce 840A and Radeon HD 6850, 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.
