I need a graphic card for my laptop and hence I need a help from you all. so do help me in giving suggestions as if which one would be the best choice for the laptop. Frankly speaking I am not at all interested in doing any kind of overclocking stuff. But I want a descent performance while playing the games like Call of Duty: Modern Warfare 2, Call of Duty: Black Ops, BioShock 1&2 etc. so please do comment accordingly over here. I am waiting for the help from you all. please do suggest me something as I know these choices are quite difficult to make but still you are experts in this field. I know you all will do it for me.
