A Titan is nothing special these days, since it came out in early 2013. It would struggle @ 4k in anything above High in the latest games.
The following cards are now faster than the Titan:
- GTX 780 Ti (£470)
- GTX Titan Black (£700)
- HD 7990
- GTX 690 (£770)
- R9 295X2 (£1000)
- GTX Titan Z (£2100)
However, PC Gamer have stuck 4x Titans in their machine, which is insane:
4x Titan Zs overclocked, will that do?
