My first real GPU cruncher was a 2nd hand nVidia GeForce GTX 260, which has come down with a broken fan a year or so ago, much to the chagrin of the power company.
It is a lot cooler in the man cave too, nowadays. How good/bad are these nVidia cards over the years? I will compare the GTX x60 series for you.
* -a, -b and -c are my designations, there are not to be found on the box of the card. You'd best check with GPU-Z what actual model you have of such a card.

Note that the OEM cards are best left alone (with the exceeption of the GTX 660). Do not buy a system with such a card included, make your own systems containing the 'real' cards, they offer better value.
Note also that the best DP performer, the GTX 560 Ti-c, does so at terrible efficiency. If you have the money to buy a card in this class and you want to go CUDA, buy a GTX 1060-b with GP106-400 GPU. Amazing (compared with the GTX 260) SP performance and rather efficient DP performance, be it at 1/32th (!) of the SP performance.
