really i dont want to change my motherboard..i just want to upgrade my cpu to the highest possible one which my motherboard supports..it is a g620 pentium processor now..i checked and i came to know that g870 is the highest model of the cpu that lga 1155 supports..and also i have only 2 gb ram..thinking to get another 2 gb and make it to 4 gb..but anyways it is worthy to upgrade my cpu to g870..i just saw an increase in cpu frequency that is from 2.6(g620) to 3.1ghz(g870)???i use it mainly for some games like nfs gta v and some more..???i have no gpu nothing...
