Hello everyone,I'am trying to upgrade my MSI GT780DX-406US (Nvidia GTX570M) GPU to 'Nvidia 3GB GTX770M MXM 3.0', my question is should I go for a Clevo or MSi brand? Not much of a tech./comp. guru person just want to plug n' play without alot of modification if necessary. Tnx All MSi - http://www.ebay.com/itm/Nvidia-3GB-GTX-770M-MXM-3-0-N14E-GS-A1-MSI-GAMING-VIDEO-Card-GDDR5-3GB-/181928863277?hash=item2a5bce262d:g:c0kAAOSwhcJWQodF Clevo - http://www.ebay.com/itm/CLEVO-NVIDIA-GTX-770M-3GB-Vedio-card-for-MSI-Clevo-and-Alienware-/321963346768?hash=item4af682cb50:g:MXUAAOSwJkJWhaFy Also what is a good 'Thermal pad' and Thermal paste' to use for this? Liquid metal good too? Tnx
