I'm on amazon about to purchase all my parts for my new PC build. First build in like 6 years. (i've been very busy). I know i want EVGA GTX 970 it has great reviews. But when I go to purchase it on Amazon...it gives me like 8 different card options..and I'm very confused by them. From basic GTX 970 to GTX 970 SSClk 2.0+...here is the link any explanation of which one is the best or any sort of description over what any of the letters and numbers after 970, would very very much appreciated.
