This thread had promise, until you went and got all snarky at the end.
Ignoring that, someone who cant tell the difference in loading times between a Revo SSD, and a normal HDD is... well not very perceptive at all. Oh wait, they actually left that part out completely, so thats 1300 pounds thats just there to superficially inflate the numbers. Strike one.
Then the CPU, lol. Another 600 pounds wasted to help inflate the numbers, or that overkill PSU thats another 100 pounds wasted. So we're down to what, 300 vs 1100? Woops, thats actually 500 vs 1100 if that site could do simple maths for the budget system. Strike two.
Finally, the test consisted of a grand total of 4 people... Thats not enough to draw any conclusion whatsoever. Strike 3
And thats ignoring all the other caveats involved when doing a highly subjective test, like the nice old games they decided to use...
Having said all that, of course different people will react differently to different image quality settings. Some people can barely notice when you turn shadows down/off. Me - I see it straight away and cringe, it destroys the experience for me. Others I'm sure wont mind. If you're one of those that wont mind, good for you. The easiest comparison for me actually is sound - I'll happily spend R1500 on good sound because I know how carp onboard sound is. Freaking constant high pitched whine no matter what you are doing drives me insane. Then again, other people dont hear it all all, so good for them, they save R1500. I cant, it ruins everything.
