Hello! I know this might be a nooby question , but I have a MSI GT680R with a GTX 460m and I want to upgrade it to this: http://www.ebay.com/itm/NVIDIA-GTX-660M-2GB-GDDR5-VGA-Graphics-Video-Card-for-Dell-Alienware-M17x-M18X/162103952675?_trksid=p2141725.c100338.m3726&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20150313114020%26meid%3De9c67d2fb6284da7977674c743fb568e%26pid%3D100338%26rk%3D2%26rkt%3D11%26sd%3D201591346023
My question is, would this card work in my laptop? and if it did, what would I have to change? The heat sync or more power?
Thanks!
