We have a Sandy Bridge contest running currently with weekly hardware prizes at Futuremark.
Project: Sandy Bridge
There are two categories, one for Sandy Bridge integrated graphics only using 3DMark Vantage (P) and one for any Sandy Bridge desktop CPU with a single discrete graphics card using 3DMark 11 (P).
We recently made 3DMark Vantage Basic edition free to use, so anyone can enter the contests for free, but remember to register or login to 3dmark.com so we can reach you if you win!
Weekly contest roll over on Fridays at 14.00 GMT, contest ends May 15th.
Note that as always we require Futuremark approved drivers, for the integrated series the latest 22.214.171.1242 drivers have been approved, but for AMD cards the latest approved driver for 3DMark 11 is still Catalyst 11.1.
