As you might or might not know, the Finnish top-overclocker SF3D is not only benching at the highest level, but also building top-of-the-line PCs for the Finnish PC ship Jimm's.
The latest creation, named SF3D OC Imperator, is rather impressive. Basically, you buy this PC and, well, you get a top-20 ranking in 3DMark11. Check out this video:
The system features a couple of Radeon 7970 videocards, a 4.8GHz Core i7 3930K processor and a bunch of SSDs. And it only costs about €5000!
