Can you send a link to that adaptor? Also, did you have to fiddle with the BIOS PCI settings as mentioned in the article? Any idea how this works on Linux?
Can I format links nicely here? It's a PE4L by hwtools.net [1]. And no, no BIOS fiddling was neccessary. Actually I just hot-plugged the thing first time, right into a running Windows 7. Windows Update went and downloaded the NVidia driver, required a reboot, an has run mostly flawless since then. I even see the NVidia logo in Lenovo's Energy Manager, suppose it thinks it's on an Optimus setup. Hotplug in rarely works, hot-plug out does work. I get a the usual eject icon in the systray, just the way you'd safe-eject USB devices.
I haven't even tried this in Linux. The EGPU is one reason why I chose to keep Windows native, and Linux in VMware Player, not the other way round. (The other reasons are Steam and some obscure CAD and PCB layout software, so I'm not going to try any time soon.)
If I recall correctly, am missing out on about 30% of the 3dmark points I should be getting by combining the GPU with a CPU of that speed level. As far as I know though, It's still faster than any laptop graphics chip available even today.
I sometimes seem to get a minor stutter in games, e.g. I'll lose about a frame or two every couple seconds, which might be due to the low ExpressCard bandwidth. This is game-dependent, and most games run flawlessly.
