I have a nvidia GTX 675m for sale it came directly out of my M17X R4 by a Alienware technician and placed straight into box after upgrade. It has the heatsink still attached and thermal pads so if you buy you will just have to take out your old card and insert the 675m install drivers and your sorted. I would like £150 or very nearest offer plus the price of postage. I'm willing to post abroad but it has to be through PayPal or cash if you want to pick it up. Just PM me and grab yourself a bargain
