I have recently switched to the sandy bridge and now I am buying the rest of the parts. There was no problem while getting any of the parts but when it comes to CPU cooler then I get stuck with Corsair A50 is 19.99 and A70 is 27.99. Now I am not able to decide that which one will be better for me and that is the reason that I am posting this over here so that I can have some replies from you people. If you have any suggestion for me then please post that over here. I will be thankful for all the replies for this.
