Hey, we almost have the same GPU, Pretty nice. Mine has a very minor overclock (came from factory, look up GTX 750 Ti SC On google)
Currently, I've got 4 computers with a dedicated gpu. Best one is a ati rx580. Next best is a GTX 1050 ti And a GTX 750 ti. Last but not least a laptop, with a GTX 860M Got all 3 desktops bitcoin mining right now, Making $1.50 to $2.25 a day.
Had a Sapphire R9 390 OC before that died, now have a PCS HD 7970 v3 which for £120 in the mining craze is great value for money (both ran/run the game at 60 FPS on max)
GTX 570 HD which is still very capable, I am able to run battlefield 1 with a mix of medium and high settings quite well
Got an rx 580 8gigs and I'm just pissed off that, with hardware a little bit worse than the gtx1070, it only achieves 1060 level of performance because of nvidia policies with their softwares...
R9 380 X (little more/less power than the GTX960, in some situations) with 3770K Time for an upgrade lol, not bad for coming up to be 3 year old card.
Good ol' GTX970 G1 Gigabyte version, does really well. However in some situations my laptop's GTX1060 does better.
