Ok, so I'm a noob to this forum, so hello! n glad to see there's interest in the G73SW. I picked up one used that came with the under-specd 460m video card(the under 1GB model) and just acquired an MSI 670m to plug in and try. it just got here today and I see i'll be basically making my own heat sink for it. I just ordered some copper plating and I have a heat sink from an ASUS G75 card that is completely wrong but I can use the heat pipes and fins from at least. This will take me a bit to construct once the copper plates arrive in the mail, but I will definitely post my results. I'm curious if I need to update the vbios, I don't know yet.
I chose the 670m mainly because I got a really good deal on one, and it's rated at only 10% less performance than the 670mx. I'd have liked to try the 680 but this is closer to the power specs and I could afford it. plus, given that i'm running with the lower end version of the 460m, I should see results (if it works at all).
any suggestions? so far ive got the heat pipes, the copper plate, copper shims and ic diamond 24 to slap this thing together. and I understand alumiweld and a propane torch will stick it all together. (of course, I could just use solder also, presuming the heat from the gpu isn't hot enough to mess with that but I need to look into it a little further.) as far as I know the card is an mxm 3.0b interface so that should work fine(fingers crossed).
I have absolutely no idea about the vbios on this one, or if/how I might need to tweak it. I suggestions are greatly appreciated!!! I also wish all the other modders out there a hearty hello and good luck!!!
