The EVGA 7800GT CO is similar in appearance to the NVIDIA reference 7800GT
card. The cooling fan on the card is a 29-fin radial fan blowing air out over
the heat sink. 7800GT fans are the same as the 7800GTX's fan. The heat sink
covers the memory. EVGA names this card the e-Geforce 7800GT CO. CO stands for
Copper, as the card has an all-Copper heatsink, allowing for cooler running
as compared to other cards with different metal as the material. To some people's
way of thinking, CO is meant to stand for the symbol on the Periodic Table.
The symbol for Copper is Cu on the Periodic Table.
 
 
All 7xxx series of cards are PCI Express native cards. Intel announced their
915/925 chipset last year, introducing the 3rd Generation Input Output interface,
otherwise known as PCI Express to mainstream computers. The first NVIDIA cards
were not designed to operate on the PCI Express bus, requiring a HSI (High Speed
Interconnect) bridge chip to run. Later cards integrated the controller on the
die, allowing the cards to work without the bridge chip. Length of the 7800GT
card is about the same as a 6800GT of last year, making for easier fits into
most ATX cases than the 7800GTX card, which often requires some rearrangement
of drives, as the card reaches the cage of most cases.
 
Modern video cards require a lot of power to operate at full speed. PCI Express
x16 provides up to 75W of power to the video card, more than 5x the power of
AGP 8x. 7800GTs and 7800GTX cards require more power, forcing the manufacturers
to include a 6-pin power cable to provide extra power. Input Output ports on
the 7800GT CO are typical of modern cards. EVGA includes two DVI-I connectors
and a TV-Out connector, allowing for dual monitors to be utilized with NVIDIA's
nView utility. Most monitors sold today are flat panel LCD monitors. With two
DVI-I connectors, you can use two LCDs, two CRTs or a CRT+LCD at the same time.
