Futuremark has been known to hold contests on occasion. The last one I recall was where you could win a new display for posting the highest score on the 3DMark app. A new contest for 3DMark 11 is being held ahead of the launch of the software this week. The new contest is open until the launch of the software.
All you have to do to participate in the contest is hit the source link at the bottom of this post and make your guesses. The person who comes closest to the correct 3DMark 11 score for each of the three test systems at the specified settings will win the mainboard and video card from the system.
You can only use one email per person, so you can't guess with 100 different email addresses. Presumably, they are tracking IP addresses. The systems include MSI N450GTS Cyclone Power Edition video card with the MSI H55M-E33 mainboard in the first system run at entry pre-set. The second system is an MSI N460GTX Hawk video card with MSI P55-GD85 mainboard. The final system is an MSI N480GTX Lightening with an MSI Big Bang- XPower mainboard.
