replacing g74sx motherboard

Hey all! I've been banging my head hard over the past two days trying to figure this out. My g74sx-ah71 became bricked, bad. I tried to reset the cmos
And all that and nothing. I know that i can sell the laptop for parts and get another but that's not in the budget. But I'm wanting to replace
The motherboard and the only ones of my exact model no longer exist. So I've been bouncing between a few that seem exactly similar but
Different.

These are from my understandings, if I'm wrong please correct me.
I'll have to move over the cpu so the socket has to be compatible and the GPU is the same in them all, so I hope.

My motherboard -- i7 socket s989 , 3gb GPU memory
60-N56MB2800-B06

Option #1 -- i3/i5 socket s989 , same GPU memory
60-N56MB2800-B14

Option #2 -- i7 socket 989 (not s989), GPU same
60-N56MB2800-B05

Option #3 ? Is there another possible match?

Please help me out as I'm losing it!!!

Each chip is 256mb. The 3gb board has 6 on front, 6 on back. 256x12=3072 or 3gb.

The part number of my original board was 60-N56MB2800-B06

The part number on a 2gb board that I was going to borrow zif connectors from was 60-N56MB2700-B14.

The part number for the 3D version of the board is 60-N56MB2900. I'd stay away from the 2900's they could have a different connector for the video cable.


So just to recap

2700 - 2gb version
2800 - 3gb version
2900 - 3gb 3d version (probably a different video connector)

These are the only numbers you should watch out for.
