Hey everyone, I am soon to be getting a alienware x51 for Christmas. It has a gt640 in it which just cant cut it for bf3 or Call of Duty. The power supply is a 330 external and I would like to know what video cards can fit and work in it without having to upgrade the power supply.
Actually the GT 640 the X51 uses is not the same as retail ones, for starters it's GDDR5 while retail is GDDR3. IT performs about the same as a GTX 550 ti and HD 7750.
Also he does not need to upgrade his PSU to use a GTX 650 in his X51, how ever if you plan on using something as a GTX 670, than you'll need an X51 with a 330w PSU which you can buy.
