You will notice a HUGE difference in scaling resolutions. The card is 1GB x 2 ... 1gb per GPU, you have to read article as to how it is broken up.

Two GPUs
One board
Radeon HD 4870 cores
PCIe 2.0 bridge chip
GDDR5 memory
HD 4870 clock speeds
1GB buffer to each GPU for 2GB total (this was updated from the original text that indicated 512MB per GPU)
1x8-pin PCIe and 1x6-pin PCIe power connectors
Remember the HD 3870 X2 design? Yeah, pretty much like that.

I like to also not the CPU that was used was a Intel Core 2 Duo Extreme X6800 2.93 GHz, which of course a Quad-Core at 3.6ghz would see higher scores in 3dmark Vantage and Other Benches like it.

Moboy67's rig for comparison is a 3.6ghz quad-core build and in Vantage he scored 14,000 + with his 2 x 4870 cards.

Just keep in mind system builds will hinder or better scores and FPS.

There is more comparisons with different games within that article.

2 x 4870's in CF performs about the same as the 4870X2 card, but it is a better solution for a future upgrade if desired to buy a 4870X2 card instead of 2 x 4870's as down the road a person can get another one and have a 4 GPU setup.
