I had X5000/20 and had x5000/40 and have a G5 Quad. im sure G5 Quad Morphos will kill the two A-EON overprized machine many times with same Morphos version and same GPU.
by the way i will do a fast test try to boot mos 3.10 on my quad with radeonhd ... just for see if something will happen

A comparison X5000/40 vs G5 Quad same gpu Linux
