I can't completely agree Sehund. Time will tell how efficient the AmigaOne is at gaming. Will an AmigaOne with a Radeon 8500 beat an AthlonXP 2100 with a Geforce4 at Quake 2? Not bloody likely. Will it give a surprisingly strong showing? I do believe so! Also using Quake II as an example, CPU speed isn't the #1 factor, the GFX card and drivers are!
I remember a while back on Tom's Hardware they proved that a 700Mhz Athlon with a Geforce2 had nearly identical preformance with Quake3 as an 1.2Ghz Athlon with the same Geforce2.
If we are blessed with mature lightweight drivers and optimised game ports, the gap between the highest end PC and our little AmigaOne shouldn't be too bad.
