If people here are interested, I tried low cost e-gpu setup and converted by 2011-12 laptop into media/moderate gaming setup. Most would already know but for beginners it basically adds external graphic card to laptop to make it gaming capable because processor power of 2-3Ghz clocked processor is enough if you have good enough GPU.
Total I spent about $250 to buy following 3 items during black friday:
1. GTX 1060 3GB EVGA
2. 500W EVGA
3. EXP GDC 8.0+ version.
My laptop is dell l502x having i7-2630 processor with 8GB RAM. Now with e-gpu, I get 50+ FPS on ugine heaven and valley benchmarks 1080p (before it was like 15-20 FPS on 720p with internal gpu). I am currently playing Tomb raider 2015 and monster hunter with around 45 FPS which is good enough for me. Good thing is that it saved me from buying another laptop $900 cost for another 1 or 2 years and I am very happy with investment.. however please make sure that you laptop has been modded by someone before successfully and steps are clearly listed.
Also the EXP GDC customer support is absolute crap, so if it does not work it is money thrown away.
