The EVGA GeForce GTX TITAN X uses NVIDIA Maxwell architecture instead of the newer Pascal one. It's one of the best performing cards on the market, capable of extremely high-resolution gaming. It has a stylish aluminium exterior and the card is amazingly power-efficient. Though an overkill for regular 1080p gaming, the card handles the newest games in very high resolutions and maximum detail without problems.

Pros
Pro Liquid-Cooled GPU Blocks
A liquid GPU block for the Titan is a must. the card is very fast but it gets hot very quickly, even at idle. The liquid block will reduce an extreme amount of heat produced by the Titan. (A good liquid block, Installed correctly, (even SLI) will keep GPU Temps. at 25-30.
Pro Fantastic performance
The EVGA SuperClocked GTX Titan can handle games at insane fps at 4K resolution. The following games were running at 4K with the highest graphics settings: Dirt 3 runs at 92fps (the Gigabyte GTX 980 managed 80 which was the next highest), Grand Theft Auto V ran at 59fps (the next highest - Gigabyte GTX 980 - ran it at 40), and Thief ran at 41fps (2nd place only ran it at 31), Tomb Raider ran at 62fps (GTX 980 and R9 290X run it at 41). These are all fantastic scores.
Pro Overclocking friendly
This SuperClocked Titan X has been further overclocked to 1252Mhz base, 1341Mhz boost, and 19023Mhz memory which can improve in-game performance by around 7%.
Cons
Con Annoyingly loud (especially when overclocked)
While not measured in decibels, one reviewer mentioned how he "often noticed fan noise while testing and while overclocking it was annoying at times".
Con Insanely expensive
For the price of this card you can buy a lot of things more useful than a graphics card, especially when GTX 1080 cards offer so much for well under half the cost of a SuperClocked EVGA Titan X.
