My new Lenovo X220 laptop should be arriving soon. While it has a nice i7 CPU, it only has only has an integrated Intel HD 3000 for the video card This severely limits 3D performance, therefore I will be adding something known as a DIY eGPU -or- DIY ViDock.
This is a simple little project that is similar to the commercial “ViDock” product but at a lower cost and potentially with more capabilities. Basically it is connecting a desktop video card to your laptop
for use in gaming and other similar intense 3D tasks…
PS The X220 is ideally suited for this task but there are lots of other notebook options out there too.
If you are interested in a fun project like this for your X220, here are some links that I hope will help!
#1 Best post for X220 owners, shows details and gives specific info on the X220 and a diy ViDock:
NOTE: I believe the only X220 BIOS version that works (so far) with eGPUs is: version 1.11 See more info here:

Good post with info for other systems too:

This is a great place to start on this project… lots of howto and good info
DIY eGPU experiences – INTRODUCTION (start here)http://forum.notebookreview.com/gaming-software-graphics-cards/418851-diy-egpu-experiences.htmlThe Let’s figure out how to make a ViDock thread has produced a PE4L and a x2/x4-link capable PE4H product, either of which can host a PCIe RAID, soundcard or a desktop video card. This thread is dedicated to the practical application of these products to attach a desktop external GraphicsProcessing Unit to a notebook via a expresscard, mPCIe slot, or Thunderbolt port. Ideally, this thread is a place for users to share installation and performance details for others to duplicate or reference.
Which video card to use as eGPU?
This is of course a very personal question since each persons video card needs are different. However, I can address one issue: which brand?!
My recommendation is NVIDIA. For the simple reason that NVIDIA has Optimus for switching between integrated/discrete video cards. In an eGPU setting this means that with certain configurations you can have the eGPU output to the internal LCD (with no additional cabling/adapters required other than the expresscard -> dock cable).
As far as I know AMD/ATI has no comparable capability when it comes to a DIY eGPU setup. Likewise, a lot of the example configurations out there are using NVIDIA instead of AMD. So that is why I recommend NVIDIA.
When it comes to a particular GPU recommendation, the NVIDIA GTX 560 Ti seems to be a popular choice. However, if you have access to an older GTX 460 (as I do) I would recommend just sticking with it since it will do a similar job and you won’t be out any extra cash!
HEXUS.net – Review :: NVIDIA GeForce GTX 560 Ti vs. GTX 460 1GB – at the same clocks : Page – 1/9http://www.hexus.net/content/item.php?item=28691&page=1Knowing that the GTX 460 GPU’s specifications have been set very conservatively and that most can run at the 822MHz/4,008MHz clocks of the GTX 560 Ti with nothing more than a quick dabble in an overclocking program, we set out to investigate just how a Ti 560-clocked GTX 460 1GB would perform. Doing so provides a good indication of architecture-to-architecture differences and will, we hope, give present GTX 460 owners an informed opinion on whether an upgrade is necessary.
Other X220 performance tweaks: 1866mhz RAM on X220 (and SC2!)
To me these improvements look like they are related to going to (2) 4GB sticks of memory, whether they be 1333mhz or 1866mhz… but you can read the threads and see for yourself!
