Theres only a couple decent g.skill kits that will do that though. I think if you're gonna go i7, you should go triple-channel and get some nice ram for not that much more. The OCZ Platinums are about $100 for 6gb ddr3 1600 and great timings. You can't really go wrong there.
The g.skill kits i found were 4gb ddr3 1333 @1.65v for about $60
