ASUS ROG Xbox (i.e. "the white one") + PCSX2 and RPCS3 = ?

ASUS ROG Xbox Ally (i.e. "the white one") is currently on sale on Best Buy so I've been considering buying one to run PCSX2 and RPCS3 cause I have a lot of backlogged PS2 and PS3 games I'd like to replay... any experience?

PS3-wise I'm not going to attempt any demanding games such as MGS4, God of War, GTA4, Killzone or Call of Duty... mostly just puzzle/RPG games or Skate 3 and maybe the occasional Street Fighter...
