Sory i know this is impromptu, but have been following this thread for sometime now. But just decided to give it a try Hence Just registering. I have an old HP Dm4 1165 dx laptop with four gigs of RAM , Intel HD Graphics, Windows 7 OS with a pre Core i5 450m (2.4 Ghz dual) Pre-SandyBridge processor.. It doesnt have an External PCI Express card slot but I plan to take out the Wireless Card (mPCI-e slot) for this purpose. I also plan to get the PE4C (Specifically PE4C-PM060A V3.0) from hwtools.net . From my Studies I feel I can use the x1.1Opt or X1.0 Opt to get "5.0 Gbps" with the Internal Gpu. Can you please recommend someone who has successfully run a similar setup with the same specs to ease my Setup of the components and also recommend a RECENT compatible Nvidia Card to get (Incase I get a PCIe 3.0 compatible Laptop in Future). Power should not be an Issue as i have loads of Atx power packs hanging around. Thanks In advance
