Hey, I have been wondering since I picked up my 760 (EVGA GeForce GTX 760 4GB Dual FTW ACX) if I should step up to the 970 (EVGA GeForce GTX 970 FTW+ ACX 2.0+). Would it be worth the $150??

The 40-50% increase chart that was post refers to a 2GB version of the 760. Seeing how I have the "top of the line" GTX760, the 40-50% improvement seems like an overstatement. 

I don't see the performance jump in the numbers. See below for the comparison. The only thing that is in the 40-70% range is the CUDA cores number, and I don't see that causing such a performance jump.

Performance

NVIDIA GTX 760

1152 CUDA Cores

1085 MHz Base Clock

1150 MHz Boost Clock

104.1GT/s Texture Fill Rate

Memory

4096 MB, 256 bit GDDR5

6008 MHz (effective)

192.2 GB/s Memory Bandwidth

Performance

NVIDIA GTX 970

1664 CUDA Cores (+53%)

1216 MHz Base Clock (+12%)

1367 MHz Boost Clock (+18%)

126GT/s Texture Fill Rate  (+21%)

Here a 970 gets 59.90 frames per second and a 760 gets 30.30 fps.  So 59.90 / 30.30 = 198 % which is a 98% increase.
 
And just so you know, when it comes to GPU power, there are two main factors.  One of them being Cuda Cores, the other being the Clock speeds.  So having lots more Cuda Cores at higher frequencies will net you a big gain.  Also the Maxwell Cuda Cores in the 970 are more powerful/efficient than the Kepler Cuda Cores in the 760.

Jump is about...17% Difference in performance

Where is this 17% that you are getting??  The 970 is at least 75% more powerful than a 760.  I personally went from a single 670 FTW to a 970 FTW and got almost double the performance.
 
And the chart using the 2GB doesn't matter since extra VRAM does not make the card any faster.  The extra VRAM only helps when the game needs more.  If the game uses less than 2GB, then there will be no difference at all between the 2 and 4GB cards.  And that chart is showing that the 760 is actually 57% of the 970, not that there is a 43% increase from 760 to 970.  It's showing a decrease of 43% from going from a 970 to 760.  If you put it in the perspective of the 760 (making the 760 the 100%), then the 970 would show 175%.  Meaning that going from a 760 to a 970 will actually be at least a 75% increase.
