If you have zero experience disassembling laptops, you might want to consider having a computer shop do the upgrade for you (Not GeekSquad) If you want to do it yourself, you can download the Dell service manual for your laptop and follow the disassembly instructions. To upgrade to any Quadro card, you need to make sure that your Heatsink part number matches the one in my previous post.  If it does not, make sure to order one with the part number : YJNJK.  If it is brand new all of the correct thermal pads should be pre-installed. The easiest upgrade with a big performance boost would be the Dell Quadro M5000M 8GB card (part number : 1JY2V).  This will require no driver modifications, just install the Nvidia drivers and be on your way.  I have had no issues with any of the laptop GPUs that I have gotten off of ebay.
Hello every one, I'm currently using the product Dell Precision 7710 for 4 years. The VGA has been broken as per dell technician has told me and asked if I want to replace the same card which is AMD FirePro 5710. I has asked them can it be replaced with stronger one but they keep telling me that it can't. Luckily that I do not beleive in them and check that the laptop could be support to nvidia quadro m5000m. However, I want something more so I would like to know if my laptop could handle a more powerful VGA card or not. For like, P3000, P4000, P5000, P4200, P5200. My system is: Intel(R) Xeon(R) CPU E3-1575M V5 [NAME].00GHz and broken AMD FirePro. Thank you
