Why is pentium G series cheaper than i3 series? Both have 3mb cache but pentium g series has more ghz. Additionally both are dual cores. Why is G series cheaper. Which one would be better for moderate gaming? Would a H61 mobo like this one --->Gigabyte Core i753 H61 LGA1155 DDR3 PCIE SATA MATX Motherboard GA-H61M-S2H be able to handle a pcie x16 card like a ATI 6950 GPU? Both (well some i3 have hd 3000) have hd 2000 graphics too.
