Considering building a laptop.

[Moline]

Hi! I am considering building a laptop designed for Dolphin and I was wondering parts you guys recommend I use for it in order to get the best performance out of Dolphin. I am currently using a 2014 Dell Latitude E6530 with Intel Ivy Bridge with Intel Core i5 and Intel HD 4000 Graphics, and while it runs all the games that I play nearly perfectly (there is some minor lag here and there), I noticed on Super Paper Mario that due to a graphical glitch, I cannot progress any further in World 1-4. Basically, there is a spot where I need to use the Thrower Pixel to hit a switch, but for whatever reason, he disappeared when I entered the room with said switch and pressing 1 does nothing, rendering me stuck. Going back to the previous room where he was previously visible does nothing as he now does not show up in that room either. I am attributing this to the Ivy Bridge processor as this glitch, as far as I remember, did not occur on my Haswell Dell Inspiron tower. Any help you guys have would be greatly appreciated!
