content: Hi guys,I'm considering buying a new PC - preferably a notebook - when working/gaming/doing similar stuff I'm mostly at my desk anyway, when I'm relaxing I'd like to lay on the couch like the fat lazy guy that I am.I'm looking into external graphics cards, because I enjoy gaming and a good GPU is advantageous for CAD/CAE applications. I currently have a Dell XPS 17 with an onboard NVIDIA GPU and I've been happy with it, but the notebook is a weighty beast with no room to upgrade the card, etc. Basically there are limitations to what you can stuff in a notebook. Also, the notebook was pretty pricey and the age is beginning to show.So, I'm looking into an external graphics card as a means to get the best of both worlds with a few tradeofs. I'm hoping that it would work like a plug and play device - basically I'd just dock my computer onto my desk and I can enjoy the improved graphics.Do you have any experiences/opinions/warnings/praise for this kind of setup?The rest of the system will be pretty powerful (in notebook terms), lots of RAM and a good CPU.Thanks,David

content: I have done a DIY version. The main disadvantage is on the software side, since the eGPU uses a separate X server. I have a few scripts to make it usable, but I would probably have to actually use it regularly to refine them to be "production" quality. (For now, I only use it the rare times when I travel.)

content: How about USB to DVI adapters? I use two of them at 1920 x 1200. There are a bunch of different ones out there:https://www.startech.com/AV/USB-Video-Adapters/USB-to-DVI-Multi-Monitor-Adapter~USB2DVIE3It's good enough for Altium, PDF, etc. even with zooming, panning, and such.I don't do 3D real-time games, and generally they aren't recommended for that kind of thing. It would get choppy and laggy. Otherwise it's almost the same response as the built-in screen.

content: I just got a alienware 17r4 and it has a option to get a "alienware graphics amplifier" now, granted I will prolly never need such, as this has a nvidia 1070 in it. but the option is there.

content: Integrated graphics is getting better and better as time goes on. nVidia even dropped the m on all of their mobile products as they say the difference is so small, it doesn't matter.While external graphics are nice for upgradability, upgrading and laptops are normally mutually exclusive. There are exceptions, there are graphics cards you can sometimes swap out, but it remains pretty much the same, they are not meant for that.To be honest, though, grabbing a notebook with a 1060, 1070, or 1080 should last you at least ten years on CAD, and I am surprised that your current device isn't good enough for that.Heck, even though my experience on CAD is minimal, I would have no problems using modern CAD software on an FX-55 with a GTX 7800.Just some thoughts.

content: The gaming performance on the new Surface Book 2 which has a (on certain models) a discrete GPU in the keyboard section (CPU is in the display part so it can be used like a (large) tablet) is pretty amazing. The top model has a GTX 1060 with 6GB of memory! Of course, it doesn't come cheap.

content: Thank you for the opinions so far guys.QuoteIt's good enough for CAD/CAE - I've got no problems there - I'm not exactly designing the new Tesla :-) . The problem arises when I want to play something like Fallout 4 (however disappointing that was) or some other fresh game. I've been also poking and prodding NVIDIA CUDA and that's fun as well :-)QuoteNah, the point here is not another screen, but rather graphics acceleration.QuoteNice build :-) As to the software part, I'm a windows user, so I'm not sure how that would work.

Unless you need a LOT of compute horsepower and a multiple GPU setup its a lot easier to just buy a higher end laptop, they typically support 3-4 monitors these days.
