Keep that in mind, but most of the latest generations AMD and Intel based motherboards are compatible. Please check with the motherboard manufacturer whether or not it is SLI compatible. An SLI certified motherboard is an nForce motherboard with more than two PCIe x16 slots or a certified P55, P67, Z68, X58, Z77,Z87 or a X79 motherboard.A Crossfire compatible motherboard is pretty much ANY motherboard with multiple PCIe x16 slots (Gen 2.0 or higher) that is not an nForce motherboard.In today's article we'll use two way SLI GeForce GTX 780 graphics cards and thus two AMD Radeon R9 290 cards. You could for example place two or more AMD graphics cards into a Crossfire compatible motherboard, or two or more Nvidia GeForce graphics cards in SLI mode on a compatible motherboard. Honestly, two GPUs in most scenarios is ideal in terms of multi-GPU gaming performance, always remember that.

The reality is this though the more GPUs, the worse the scaling becomes and the more driver and CPU bound issues you will run into. This way, you effectively try to double, triple or even quadruple your raw rendering gaming performance (in theory). Both Nvidia's SLI and AMD's Crossfire allow you to combine/add a second, third or sometimes even a fourth similar generation graphics card (or add in more GPUs) to the one you already have in your PC.
