okay, so the computer I currently have by my desk here is a GT live 2013 so it's board might be newer than what was available during the 2010 time... thus, may not have built in driver support in 2010 for the newer board.
I will post the model # for posterity's sake.
This GT2013 computer has an Intel DB65AL motherboard with 1 GB factory supplied ram.
so I can absolutely confirm that model board will work with GT versions 2013/14/15/16 and so on into perpetuity. I cannot confirm any backwards compatibility from 2013 as I'm not sure when driver support was added.
as for your suggested board...
I know of a D915GUX board, i'm unsure of the year it was introduced. it is a confirmed GT model number though.
i'm, not sure what the difference between the D915GRV and the D915GUX boards are, but it could be quite significant... it could be inconsequential. it could be as trivial 4 vs 2 sata ports....it could be a totally different northbridge chipset to different CPU compatibility... this is the reason intel boards are kind of a bugger to source...they have literally endless variations of the same board. for our setup here, you pretty much have to source an exact replacement model number.
I'll keep digging up model information and post it here as I get it.
