Earlier I was having the GTX 580 but now I am planning to get GTX 680. Currently, I am having game at 192x1080 and ‘I want to ask that what are the benefits and improvement that I will get if I go for 4gb over the 2gb. I have read this somewhere that the 4gb card is just for the resolutions higher as compared to the 1920x1080. I found that the card is having 8 phase pwm and you know that what it means by that and what are the benefits that it will take to table over the GTX 580 SC 5 phase. I wish that I could get some suggestion from the people over here. So if you have some suggestion for me then please let me know that. I really need some good suggestion at this point of time. Please reply ASAP.
