Recently bought a EVGA GTX 750Ti($168 CAN after mail-in) but there is a sale ending tomorrow for the same but in a 960 OC edition for $60 more ($228 after mail-in).  Will I see any big difference when paired with a i5 4670 using 2 cores or at this point does the CPU become the bottleneck and thus not worth the upgrade?

It looks like the 960 is about 50% or more faster.  CPU bottlenecks are heavily dependent on the game.  Some games it doesn't matter some games it does.  I would look at the games you plan on playing and find out if they are heavy CPU users.  Having the faster card now and upgrading the CPU later if you need to may be a possibility.

 

If you don't have any issues now playing games you could also wait and you could get a better deal down the road.

Well I did the math. I think I am pushing my luck enough already with my Silverstone STX 300W power supply. GTX 750Ti pulls about 60W vs. 128W for the 960.  Intel i5 4670 at 150W if at 100% load and an SSD and 4 hard drives.

Stick with the 750Ti. I considered doing the same but after research, there's not a whole lot of improvement going to the 960

The 960 would probably give you a healthy boost, but by how much, not sure exactly, and as you've stated, it may be pushing your PSU too far.  The GTX 750 Ti is definitely the sweet spot in price for performance at this point.

Yeah sticking with the 750Ti. It's plenty of power for what I am playing.
