Could you please make the guide? I am very interested! I have a Gtx 970 in my X51 R2 and it has just started to constantly crash due to the power supply. I would really love to see your guide as i am pretty much a amateur at knowing what to buy or replace but you seem to know your stuff. Do i need a new motherboard? Is the power supply that you put compatible with the Alienware X51-R2 motherboard? Please respond soon!
