I just bought my first Alienware it is an M17X ( R1 I assume ) P01E. I have already ordered the wrong battery once and the wrong power supply twice. I now realize I need the 240 watt 19.5 volt 12 amp power supply. What I'm trying to find out is, can I put an Intel core duo extreme x9100 in it & what gpu options do I have if I keep the original r1 motherboard? I believe I have 2 gtx280m's & from what I have read they won't run modern games. If I can get it to run warframe & bf4 I'll be happy. Also how many gb of ram can the r2 board handle, cuz I want more than 8.
