I am comparing the Galaxy 65NPH7DN7WGU GeForce GTX 650 Ti BOOST 2GB 192-bit GDDR5 PCI Express 3.0 SLI Support Video Card (http://www.newegg.com/Product/Product.aspx?Item=N82E168...) and the GIGABYTE GV-N65TOC-2GI REV2.0 GeForce GTX 650 Ti 2GB 128-bit GDDR5 PCI Express 3.0 x16 Video Card (http://www.newegg.com/Product/Product.aspx?Item=N82E168...)... The Gigabyte has the faster clock speeds and has more Over Clocking Potential, but the Galaxy has the 192-bit Memory interface. will the bandwidth of the memory give me better performance, or will the OverClocking?

More about : faster clock speed higher memory bit rate

The 650ti boost is a far better card as it does have increased memory bandwidth through 192 bit over the 128 bit of the 650 ti. The 650 ti boost is basically a gimped gtx 660 and also has more power period than the 650 ti.

so the memory bandwidth is more effective when it comes to performance?

I really am no expert, but essentially yes as long as the memory bandwidth is not excessive for the amount of memory and computational power more is better I believe.
Edit: Sorry, misread and regarding your post, it is more that the computational power of the card (cores and so forth) needs a corresponding amount of bandwidth which is generated by the size of the interface and the speed at which the memory runs as to be not limited by either the computational power of the card or the memory bandwidth and/or the amount of memory a card possesses.

I probably just butchered this so don't take this to heart. If someone could help do a better job explaining I would be eternally grateful.

Edit 2: here is a chart to use as a general guideline when comparing gpus in terms of performance.
