Motherboard to ddr2+3

hi
im looking for motherboard that will take my cpu e8400 intel and ddr2 memory but will take also in the future I5 INTEL CPU with ddr3 memory
can someone point me at one mb type that can do this job?
thankx

There is not one. These CPUs take 2 diffrent socket types. There is no such board.

Thent

There used to be a motherboard with ddr2 or ddr3(not both) options. It was not a great seller.

Regardless, the price of DDR3 is so cheap, that it is not worthwhile trying to reuse DDR2 ram. In fact, since DDR2 is more expensive, it has a relatively good resale market.

If you are going to buy a new motherboard, you might as well buy a new cpu while you are at it.

The lowly G620 @$70 is a better performer, and you can sell the E8400 on ebay for almost that.

Asus is considered to be a top of the line MB and has a much larger selection than Gigabyte in the 1155 slot category. Just look at you vendors' site under motherboards and pick something that fits your needs and price range. That is, crossfire or SLI, RAM slots, SATA ports, USB 2 and 3 ports, etc.

i couldnt find board with 775 socket together with the I5 socket so i bought new intel I5 2500K cpu with new asus board.
the ddr3 are not expensive but i have no another question, do i need much better power suply if i have a basic 500w now?
does the i5 cpu needs that?
