I currently am using a msi GT 240 1gb gddr5 and so on, and I have a Cooler Master GX 750. I would also probably be gaming on a 1080p. I seriously would like to upgrade since its showing its age, and it is quite loud(The fan speed cant be changed for whatever reason). $200 is the budget that I would like to stay at, but if there is something dramatically better for less than $50 more, I could find the extra money. I have seen the GTX 480 on newegg, but I am aware of how power hungry it is(I want something thats at least pretty efficient). Any suggestions?
