This thread serves as a roadmap for those who wish to attach an external Graphics Processing Unit (eGPU) to a notebook/laptop computer. Connection may be achieved through an ExpressCard, mPCIe slot, or Thunderbolt port.This thread is a place for users to share installation and performance details for others to duplicate or reference.
Note: For those running Windows 7, you can install the eGPU without rebooting your system. Simply and the turn the system to standby system and attach the PE4L. Your system will return to its desktop presets once it detects the PE4L. You will immediately see a significant upgrade in the performance.

For example. a Inspiron 1440 using the x1E tweak saw 3dmark06 go from 866 to 9551. RE5 benchmark went from an unplayable 4.1FPS to a very playabe 60.9FPS. The HP 2560P's x1.2Opt link saw 3dmark06 increase over 4 times to 18340 and RE5 gave an average of 148.3FPS(!!), even allowing the internal LCD to be driven by the eGPU.
- Inexpensive: US$92-shipped PE4L with HD5770+120W=$200, GTS450+120W=$160, GTX460-1GB+430W=$210, GT430+72W=$130, HD5670+72W=$140. Add $66 for a x2 capable kit using a PE4H.
- can be used on any system with an accessible expresscard OR mPCIe slot
- has inexpensive eGPU enclosure examples if you want an enclosure
- 10 times or more increase in video performance
- can have Internal LCD-only setup: NVIDIA Optimus or Ultramon/Chung-Gun method.
- provides additional HDMI video+audio, s-video and VGA out

- allows multi-monitor connectivity:
- AMD Eyefinity to provide up to 3 LCDs attached to any HD54xx or better card.
- Drive up to 6 LCDs to using a HD7xxx or better card supporting Eyefinity 2.0
- AMD FirePro 2450, 2450x1, and 2460 to drive up to 4 monitors from a low power card
- NVIDIA Surround can connect up to 4 simultaneous LCDs.
- easy, on-demand attachment without a reboot if running Win7
- can be reused after a system upgrade, or shared amongst multiple systems
- see an extra 30-60% in performance when attached to an expresscard 2.0 system, or do a x2 1.0 setup
- provides an additional USB port when connected to expresscard slot
- Time-share your desktop video card b/w your desktop and notebook system.
- perform CUDA/OpenCL processing for applications that support it like Adobe CS5/Premiere [NVIDIA graphics only]
- ability to use physX/hybrid physX & game detail
- components can become a stepping stone to a full deskop system if want higher performance
- requires a 12V PSU to drive the desktop eGPU
- requires an external LCD/CRT/TV to connect to display at highest FPS
- may require booting DIY eGPU Setup 1.x from a disk image or USB stick to overcome error 12 issues
- restricted bandwidth: a x1/x2/x4 link represents 1/16, 1/8 or 1/4 the bandwidth of a x16 slot.

Spoiler[Aug-2014] BiZon (RU) selling US$274 EC-to-Thunderbolt parts for US$610, undermining the cost-effectiveness of eGPU solutions for Russian Macbook customers. A Rip-off alert issued here.
[June-2013] Randy Case @ Harmonic Inversion Technology (US) collected but then walked away (stole) 16-months worth of Setup 1.1x donations he received for 'development purposes'. REF:Summary: dealing with HIT's abandoned eGPU commitments [customer thread]. Note: Randy was previously a Villagetronic distributor but supposedly switched to distributing DIY eGPU hardware due to a fallout with the Villagetronic CEO.
[Dec-2013] Apple/Intel (US): initiate US$170 BPlus TH05 Recall Notice thereby eliminating cost-effective Thunderbolt eGPU solutions. <-- Rectified by June-2014 release of http://forum.techinferno.com/diy-e-g...html#post98210 . Still, Intel appear to be doing whatever they can to limit application of Thunderbolt to eGPU by making vendors use 25W PCIe slots, instead of 75W or making Thunderbolt enclosures way too expensive. *Appears* to be a company survivalism/profit strategy to prevent migration towards CUDA/OpenCL GPU-based processing instead of Intel's CPU processing.
[10-Sep-2012] notebookreview.com (US) : banned nando4 (me) for ridiculous reasons from their site preventing my input into the original 9-18-2009 DIY eGPU experiences (NBR) thread I initiated and maintained. As a result relocated the main content to Tech|Infero. Notebookreview.com refuses to remove my copyright content on their site to allow unified discussion here. Instead, the mostly abandoned thread just confuses users with stale info. NBR continue to draw ad revenue from that thread, the biggest one they've ever had by a significant margin. REF: Nando4 NBR ban summary.
[Aug-2011] Villagetronic (CN), commercial eGPU vendor directs their users to the then free DIY eGPU Setup 1.x software to supplement their hardware sales, ignoring the "free for non-commercial use license". As a result the software is moved to be US$25 restricted donationware as of Feb-2012 REF: FAQ and VT breach: 1, 2, 3.
[Jan-2011] Intel (US) locks down the x1, x2, x4 port settings in their Series-6 chipsets (2nd-gen i-core) or newer making x2/x4 configurations impossible for all but the extremely technically minded individuals. Series-5 and earlier chipsets did allow x2/x4 links to be setup if the system had the right port configuration. REF: nando4 investigation
[8-Sep-2010] notebookreview.com (US) posts an underperforming Intel HD iGPU + AMD eGPU configuration in their DIY ViDock (eGPU) review rather than the superior Intel HD + NVidia Optimus eGPU one requested. That giving validity to their claim of underperformance and external LCD requirement and overall downplays it as more for amusement than as a serious competitor to gaming notebooks. Had the latter configuration been used then it would have outbenched any gaming notebook at that time except the top tier dual-GPU XF/SLI ones.
