Hi all,
Many thanks to everyone for the kind advice.
I already had off the table discussion with the concerned people about
putting-in GPUs on my own, but that is a risky way to go. Dell is offering
them additional discounts, and 2 years of additional warranty in all the
machines. I (and also University) may have issues if Dell figures will it
out when repairing.
I am also afraid that it may be possible to figure it out easily (through
logs) that which components were being used at the time of ( or caused)
crash!
But many thanks Ross, I would settle this with P4000 as of now.
Regards,
Mish
