As reported earlier Tweaktown got their hands on a GeForce 9800 GX2. Their test lab now also overclocked the card and published several performance benchmarks.

Quote: "When a new high-end graphics card comes out you like to think that a CPU with four cores clocked at 3GHz is going to do the job pretty well. Though, like most high-end cards, when we start to increase the CPU clock further, we can begin to see some really good gains in performance. So we’ve done exactly that today, we’ve moved our trusty Intel quad-core Q6600 processor up to 3.75GHz but at the same time we thought that we may as well see what we can do with the clocks on the GeForce 9800 GX2. The increases clock speeds will be what most consumers can achieve without spending a truck load of cash on extreme cooling. CPU is cooled using Corsair water cooling and the GX2 uses its stock standard air cooling."
