So in my place the price of the I7 2600 and I5 3570K are the same about 140$ . I don't know what is better for gaming and I want the best price per performance . If I get the I5 3570k I have to spend 40$ more for the motherboard Z77 instead of getting a B75. And I7 2600 only support RAM speed up to 1333mhz so my 8gbs 1600mhz can't be used on this one and I have to some how find the 1333mhz RAM which is almost can't be seen any where. Can you guy give me some suggestions ? Please help
