Onto benchmarks.

Here is our current test system.

Our test OS was Windows Vista Ultimate SP1 with Nvidia's 175.12 of Forceware drivers and ATI Catalyst 8.4. All the latest software revisions were used in our testing.

In Crysis the 3870X2's performance is not bad, not great compared to the 9800 GTX but not bad.

While Unreal Tournament 3 was definitely not a hit but the game engine undoubtedly is so we feel it's important to test. Here we see some different results across the resolutions, at 1680x1050 the Visiontek 3870X2 OC is almost tied with two 9800 GTX cards in SLI, at 1920x1200 it dips a little even with two 9600 GT SLI cards and luckily it doesn't lose much at 2560x1600 able to handle the higher resolution while a single 9800 GTX card loses it's edge in a big way.

Quake Wars is one of the last Open GL games on the market and as always with Open GL games it favors Nvidia heavily. Again though the Visiontek card beats a single 9800 GTX at 1920x1200 and 2560x1600.

Episode 2 isn't very demanding at even HD resolutions so we only tested at 2560x1600. Here the 3870X2 bests the 9800 GTX although comes short of two 9600GT cards in SLI.

3DMark is a synthetic benchmark but very popular to see hardware potential. Here we see the 3870X2 come in just under two 9800 GTX cards.
