Dont think i can cancel a buy on ebay that i already paid also. I dont think i´ll will notice any difference between DDR3 and DDR4 in stock speeds. But yea when it comes to overclocking the DDR4 will go higher. But CF with stockspeed will kick ass anyway :p .. I´m no hardcore overclockers so, just running on water.

Has anyone seen any reviews of the new 3870 DDR3 cards ? And what i can see the new 3870x2 cards using DDR3 memorys
