For the time being, at least. VR-Zone has tweaked and modded their way to a 3D Mark 2001 score of 11,199! There are lots of preparation to be done before you can get this insane score.
The CPU mods:
"CPU is XP1800+ (1533MHz) from week 40 and it did 1740Mhz at 1.85V aircooled. To run 3DMark at 2035MHz I had to increase Vcore above 2.0V and cool the chip down. The test is run at Vcore of 2.13V and I'm using custom made R404 (-45°C) waterchiller to keep the antifreeze cool. Antifreeze temp is usually at -25°C to -35°C."
And the video card:
"Here's my modded GeForce 3 with custom made water cooling. With the help of this cooling and increased GPU/MEM voltage I can overclock the card up to 310/680MHz. This test was done at 305/670 for maximum stability."
