Gigabyte GA-Z77X-UD3H REV 1.1. This motherboard is SLI capable. I have a Gigabyte NVIDIA GeForce GTX 650 Ti Boost 2GB OC GDDR5 (GV-N65TBOC-2GD) for a 3D Video Card. It's in a PCI-E 3.0 slot with a 16 bit data path. However if I add a second identical card (as needed for SLI) my data path splits in to two 8 bit data paths. 1st Question: Is this pretty common for motherboards to split the data path like this when adding a second card for SLI? 2nd Question: How much of a performance increase will I actually see? I'm particularly interested in getting more FPS (Frames Per Second) for my FPSs (First Person Shooters).

The general increase in performance for SLI and CF is usually given at 80% max. But not all games play nice with SLI/CF. It's better though than it used to be, and SLI is usually handled better than CF. I've had several SLI setups over the years. 80% seems about right from my limited testing. Occasional micro stutter is still present with both dual card setups, although not as bad as it used to be. Dual 650 Ti Boosts would probably be more susceptible to M-S than say a pair of GTX 770s or higher.

Will I see an increase in my 3D graphics performance by adding a second identical card in a SLI set up?
