Hey I got a new 970 and when taking my old gpu out I forgot to unclip the PCie slot and I pulled it off..... Im going to buy the exact same Gigabye 990FXA UD3 to replace it, will I have to buy another copy of Windows or will it be ok as its the same make of board? Or if I got a Gigabyte 970A UD3P? Cheers.
