Thanks for the info Ravenblade. This is a very interesting site. After analyzing my system on numerous games that I own and soon-to-be released games, I have mixed impression of this site. It's both helpful and discouraging. It helps you easily quantify your PC's abilities but it also may highlight your PC's weaknesses ( if you have a PC that lies in the murky middleground between smokin'n fast and snail speed ) reminding you that you need to upgrade your PC.
I couldn't help noticing the "we recommend" links that appear next to items that your PC failed which link you to sites selling computers. Makes you wonder if the results are skewed on the slow side to prompt you to visit the sponsor links.
After examing the system requirements for a wide variety of recent games, I find no rhyme or reason in these games' system requirements. Some games like Half Life 2 give you great graphics for relatively low hardware requirements. And then there's games that make no sense like the forthcoming Guitar Hero : Aerosmith for PC for which my PC could not pass the recommended requirements ( and yet passes the recommended requirements for Mass Effect, and Bioshock which have way more impressive graphics than Guitar Hero ). This sort of nonsense really turns me off the idea of gaming on a PC.
