GPU language barrier, what do these acronyms mean?

[zipzeolocke]

So I am in the market for a new graphics card and looking on Amazon there are so many different versions of the same card and I don't understand what the pros and cons are other than the price difference. a lot of the specifications are almost identical except for the kingpin addition which seems to have some of the highest numbers.

My question is what does ACX 2.0 mean? and can someone please give me a brief summary of the pros and cons, or maybe which card would recommend the most out of all of them. Keep in mind that I do not have the intention to use water cooling so recommend based on that information.

My computer specifications: Operating System: Windows 7 Home Premium 64-bit

System Manufacturer: Alienware

       System Model: Aurora-R3

Processor: Intel® Core i7-2600K CPU @ 3.40GHz (8 CPUs), ~3.4GHz

Memory: 16 GB RAM (1333mghz)

Graphics card: 2GB Nvidia GeForce GTX 680

Its type of cooler that evga uses on some of their cards.

 

Every manufacturer uses their cooler with some name.

ACX is just the cooler, the 2.0 is the second generation of that cooler.
