Specs that run Twilight Princess And WindWaker smoothly

[instantsetsuna]

Hi!
I'm planning to buy a desktop/laptop and would like to play TP and WW in it (just those two). What specs would run those games smoothly?

I've already read the minimum requirements for dolphin http://forums.dolphin-emu.org/showthread.php?tid=4 but there seems to be a lot of comments in youtube saying that TP demands higher specs.

(Naturally, I also want to keep the cost of the computer as low as possible.)
