Your CPU will bottleneck either of those cards. Don't forget the fact you will need a new power supply as well. You will not be able to easily reuse that case with a new motherboard and you will need a new copy of windows as well. Ram, hdd, and dvd drive can be reused though.
 
According to http://www.tomshardware.com/reviews/gaming-cpu-review-overclock,3106-2.html that Athlon X4 750K processor is the very entry level gaming processor, so we will see how it fairs against Phenom II X4 810.

In a very general no specific test scores,
Phenom scores 3239

vs
Athlon scores 4301

Another comparison, again not very specific test scores.
Phenom scores 3310

vs
Athlon scores 3290

Another one says that they are similar also.

At the end we should be able to conclude that both of them either runs similarly, or the Athlon wins.

Now let's look at how well Athlon X4 750K pairs up with GPU
https://www.youtube.com/watch?v=lpGfA6g0-0Y @ 2:45 and beyond, you can see that a GTX 750 Ti isn't bottlenecked by the Athlon.
In this thread http://www.tomshardware.com/answers/id-1789540/amd-athlon-750k-bottleneck-gtx-660.html they talk about how if it's a CPU intensive game, then it will be a bottneck to GTX 660

I think it's safe to conclude that if you are looking to play specific game that doesn't require much CPU power, then you will probably be bottleneck by a bit when pairing up that Phenom and a GTX 660 Ti. However, if you do plan on playing many different games, then it would be best to upgrade to CPU.
