![]() ![]() ![]() You can still run 4 Pascal GPUs, but you’ll be restricted to getting full use only in synthetic benchmarks, not games. Nvidia also does not support more than 2-way with the Pascal-series GPUs (the older cards did support 3 and 4-way/Quad). 4-way also adds a tremendous amount of heat, and poor scaling, as well as massive power draw. More cards means more work to be done, and more room for error. ![]() It’s also recommended to have proper cooling for the CPU, as there will be a substantial load on the CPU.Ĥ-way means running 4 individual GPUs together, while Quad means running 2 dual-GPU cards together. Be sure you have enough power for the additional card, and proper airflow/cooling. If you’re using a simple 2-way setup, a normal unlocked i7 will do fine (the x700K variants). This means having a powerful CPU to keep feeding the GPU information, as a lack of information will result in lag, stuttering, poor quality, and potentially crashing. This is because when you add more GPU, you want that additional GPU to run freely, and not slow down. In addition, having more than 1 GPU will almost always require you to have a high-end CPU (at least a normal quad-core i7), and 4-way/Quad SLI will require a very high-end CPU (hex or eight-core i7, or a Xeon). This is due to scaling, which does best in two-GPU setups (not necessarily two-card setups).Īdding more GPUs allows you to get more performance, but the gains diminish rapidly. SLI generally results in a 60-90% increase in framerate (though this is typically only while running a 2-way setup). ![]()
