    I've just done some self-made PE4L-like adapter :)
    Some impressions in attachements..

    Needed things:

    - 1x ExpressCard with full plugged contacts, ~5eur. I Used this eSATA-Card (Germany):

    - PCIe riser card for soldering: e.g.
    PCIx16 Slot or PCIx1 Cable-Slot
    - 1x IDE Kabel 36-wire
    also ATX-power supply and Gigabyte GTX460OC..

    Whats the matter with the electrical components on the PE4L? Only for LED-indication & some levelling of power?
    If its interesting, I can put the connector pin assignment into a pdf-file.

    One problem, when driving an external display, the 3dmark 06 benchmarks only reaches ~9100pts. Shouldn't that be ~10000/11000pts???? All with Core2Duo P8400 and 3gb of ram!

    3dmark 06 (internal lcd) --> 8126pts
    3dmark 06 (external lcd) --> 9146pts like above
    3mark vantage (internal lcd) --> 7153pts
    3dmark 11 (internal lcd) --> 2475pts

    Self-made PE4L wow, that's fun.

    Is it running at 2.0 speed ? what does GPU-Z say ?

    Your scores seem a bit low but it's with a core 2 duo so maybe it's cpu limited.

    You have amazing soldering skills. That must have taken many hours and lots of swearing.

    Kudos Sonny, that's awesome. It's highly possible that it's capable of 2.0 speeds. Can you check GPU-Z for us? (Looking at internal scores, however, I doubt it.)

    My Notebook just got GM45 Chipset, which is not capable of PCIe x1 2.0 over Expresscard, see Screenshot! Got no Laptop with newer Chipset!

    Soldering took 5h and a little nerve-racking, but it works ;)

    No one about the low external benchs??

    In attachment the connector pin assignment, maybe someone can draw it more professional?!

    Thanks kizwan! As soon as i have a free weekend I'm going to set it up and post back the results!

    Great job Sonny!
    About the low 3dmark06, I suggest that you try other benchmark/games on external screen, because 3dmark06 is severely limited by the cpu.

    Hello everyone,

    After using an HP Probook 4530s with a 5770 for a a long time, I've decided to upgrade my setup. The new card and PSU will be transferred into a desktop which I'll build when Ivy Bridge CPU's will comes out.

    I'm looking at these two cards:
    Newegg.com - EVGA 01G-P3-1561-AR GeForce GTX 560 Ti FPB (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
    OR
    Newegg.com - EVGA 02G-P3-1568-KR GeForce GTX 560 Ti (Fermi) 2GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card

    Is the 2GB version worth the extra cost? I'm playing @ 1920x1200.

    Additionally, I'd appreciate your help in finding a suitable PSU.
    As I mentioned, the PSU will power a desktop in a few months so I need something that will be able to handle that load.
    Having the option to SLI in the future is nice, but not a must.


    Thanks a bunch!
    I promise to post new benchmarks when I buy everything :)


    Edit:
    How's this? Overkill? Not worth the $$? Great?

    Depend on your desktop specification but that PSU should do OK for SLI/non-SLI build. For sure not overkill for a desktop. BTW, if you want to build Ivy bridge computer, why don't you wait for ATiAMD 7xxx or Nvidia 6xx graphic card.

    Mass Effect 3 :D
    Also, Skyrim.


    Edit:
    Thank you for the reply btw.
    Is there another PSU you would recommend?

    Hi, I have the eGPU hardware from HIT and just recently reformatted my computer, losing the egpu setup software. Seeing that I have bought the hardware from HIT, do I still have to pay to obtain the software again?
