I hope thts not the case with the gp2x, but i have had my gp32 since 2002 and OCing is the only way to really enjoy it and its perfectly fine no problems.
I see, I thought Gpx2 has two 200mhz cpus, but zodiac has a ati chipwhich would probally make it better for psx. Neo Geo hmmm I'd take that over psx anyday.
