Hey Everyone, hope you all are doing well!

So im having trouble distinguishing the 'big picture' difference between the graphics cards below:

1. EVGA 01G-P3-1460-KR GeForce GTX 560

4. EVGA 01G-P3-1561-KR GeForce GTX 560 Ti

I compared them on newegg:

and the only differences i saw was in the core clock and the cuda cores but i don't know much about graphics cards theats why im asking.


The reason i'm asking this is because i'm building a gaming pc right now and im trying to choose one of these graphics cards. I would like to get the best one for the money.

My set up right now is:

Intel Core i5 3570k

ASRock Z77 Extreme4 LGA 1155 Intel Z77
