While i'd be inclined to take the german's testing as reliable, PCWORLD??? they are terrible when it comes to anything technical, hell they got worse since they hired the "Tech-Guys", unless of course you ain't referring to the spinoff sister company of Currys & Dixons, "PCWorld" here in blighty lol
EDIT:
Ah just checked off the link, thankfully it's the USA PCWorld mag, now that's more like it, was gonna say anyone that believes the UK store I thought you ment needs thier head examined, cos there been a long list of stupidity in the branches I've visited over the years from there so called "Tech Guys" support... such as not knowing the difference between AGP and PCIE! oh how I laughed at them, my brother in law makes a point of buying his games there merely to taunt the staff when asking about the specs needed to play em, knowing fine well they haven't a clue.
