World's first Dual GPU graphics card ATi Radeon HD3870 x2

ATi Radeon HD 3870 x2 is the new year gift to gamers from ATi which is totally based on a new technology. Unlike utilizing the 2 seperate GPUs( as in nVidia's SLI and ATi crossfire ). This card takes a ground breaking leap by making out 2 GPUs in a single card. This technology has its advantages like

1. The card can sit in normal PCI 1.1 slot whereas in SLI and Crossfire you need to get a compatible motherboard for it.

2. The 2 GPUs in a single itself saves lot of power whereas 2 seperate cards will naturally require more power.

This card is also available as single GPU card HD3870 which has some difference as follows

1. The clock of GPU chip is less when compared to x2 card. HD 3870 x2 clocking @ 825MHz whereas in normal HD3870 clocking @ 775MHz

2. The HD3870 x2 has 1GB GDDR3 memory clocked at 1.8GHz which is slower than HD3870's GDDR4 memory clocked at 2.25GHz.

3. The HD3870 x2 's power is less than double the power of HD3870 due to the overhead involved in getting two GPUs to work in tandem.

This card cost sub $300.
