I would be all over that Asus TOP for its high factory overclock, cool temps, and really, really quiet fans,heavily modified PCB, with an efficient VRM design to produce low temperatures, improved voltage regulation circuitry, much better Chil controller , specially binned chip and voltage control and monitoring support that you won't find on most other non-reference cards.The thing a straight beast!However if you will be gaming on three monitors get the 4gb card.
I usually use one monitor but I also have my current card connected to my 42in tv so my nephew can watch what I play without standing over my shoulder. They're both 1920x1080 on the resolution, but eventually I may upgrade the computer monitor to a higher resolution. I've been leaning toward the 2gb one because most of the specs on it look nice. The memory was the only thing I wasn't sure about since I'm not sure how much memory most games currently eat up. I usually play games like BF3 and Skyrim and other things on my consoles so that should likely keep from needing the memory I would think but really wanted a second opinion on it. Thanks for assistance
