Hello everyone, I was wondering if anyone had any suggestions for an ideal eGPU setup for a Lenovo W520 (see signature for details of the laptop). The main issue is: I have very large 3D data sets/meshes that are very taxing (stuttering) on my current GPU. Since school/work is paying for the setup, I figure I might as well get the best eGPU setup as possible. I know the GTX 690 and GTX Titan have gotten rave reviews/incredible benchmarks. But will they be overkill for the PCI-E slot bottleneck effects? Will the GTX 780 even be overkill? Any and all help/instructions for a high-end eGPU setup for my laptop would be immensely appreciated. Thank you.

They recently stacked the GTX 690 against two 680 cards: Nvidia GeForce GTX 690 Review & Rating | PCMag.com Absolutely nuts. Figured people on this thread might appreciate.

My colleague has this exact same issue with this exact same model - it was fixed when he re-enabled the integrated Intel graphics.

Hello, First off, thank you SO MUCH for posting this super-helpful step by step guide. I need a more powerful graphics card on my Thinkpad W520 for 3D modeling with high volume data sets and meshes (current graphics card is choppy with the higher volume data sets). Therefore, I need a powerful eGPU setup. I know that you used the W530, but do you think taht this exact same set up will work with my W520? Details of my W520 are in the signature. Any help would be immensely appreciated. Thanks again. - - - Updated - - - Also I completely forgot to ask: would a graphics card like the GTX Titan or the GTX 690 be overkill since there is apparently a bottleneck with the PCI-e connection to the laptop? Thanks again.
