Alienware M17R3 question GTX580M vs other models

[Yariko]

Hi,

I have an old Dell Alienware M17R3 (2011 built, “new”A12 Bios). Back in 2014 my GTX580M broke, so I decided to put in a GTX680M, which lasted till recently. Now I’m stuck again with 8 beeps and the LCD not turning on. When I remove the card and switch the laptop on, the LCD at least turns on, so I guess it’s a faulty GTX680M. Now...back then people suggested not to go for a GTX580M due to bad thermal values, but as I’m not really using the Laptop for gaming anymore, wouldn’t a GTX480M possibly be a better alternative that lasts even longer? I heard that GTX700M’s could fit in as well, but people reported non fixable sound issues plus thermal issues. Any ideas?
