In my opinion, you're making a mistake. Not only are you not going to see any performance benefit from Quad SLI, you're also going to be hampered with 2GB of VRAM. Not to mention that you're having to buy an expensive PSU and will increase your electricity bill, assuming you're the one who pays it.

The GTX 690 was a monster of a GPU in its day, but that was a long time ago and things have changed considerably.

Assuming a worst-case scenario, the second card could draw just as much power as the first, and you're going to need a top-notch PSU and plenty of cooling to ensure stability.

I assume this isn't a gaming build? Quad SLI is utterly pointless for it and you'd be far better off selling your existing GTX 690 and buying a new, single card instead.

A single GTX690 is still a decent card and it's not even too bad on power. When you double that it doubles the wattage but not your fps so it's not really worth it.

Metro games and a few others, but the all run fine without a dedicated physx card too.

My GTX970 runs these games really well. A GTX690 should be close to the speed of a GTX970 or even a bit more so it's still lots of gpu power.

A single GTX 690 is going to be hampered by its 2GB of VRAM. For 1080p gaming today you want 4GB at least. There's also the issue that not all games will support a single GTX 690, and in that case, you'll be gaming with what is essentially a GTX 680/GTX 770, which is pretty low-spec for today.

Don't throw your money away. Sell your existing GTX 690 and buy a GTX 1060, RX 480 or GTX 1070.

you can still put 3 way and 4 way with older cards but older or not nvidia are no longer providing 3 way or 4 way support in new games. because of that even if your card still support 3 way/4way what's the point if there is no new game really support it. they might still scale to certain extend but if there is other issues (stuff like flickering object that is quite common with multi gpu or stuttering) nvidia will not going to fix them even they know about it.
