A closer look:
Right away you will notice the size different between the
HIS HD 2900XT Video Card (24cm/9.5") and the BFG 8800GTX Video Card (27cm/10.5"). The 8800gtx video cards
are a little longer and this might be an issue in some mid-tower cases. So keep
this in mind if you are purchasing a mid-tower case and one of these cards. Another obvious
difference between the two is the 2900XT video card has a cooler which occupies
two slots and the 8800GTX video card has a Danger Den water block and occupies
one slot.
While a water cooling system is required to operate the BFG model, it's
completely silent. Of course an optional waterblock (Danger
Den) could be installed on the HIS model if so desired. Both video cards have
two DVI connectors, but the 2900XT has a DVI-HDMI dongle that carries both video
and audio (5.1). Each video card also has a Video In/Video Out connection for
connections like; HDTV (component), S-Video, etc.
Both of these cards require a
quality power supply in order to ensure system stability. It's worth noting that
the 2900XT video cards require more power than the 8800GTX video cards. Both the
2900XT and 8800GTX require two 6pin PCI Express power supply leads, but in order
to enable the 2900XT overclocking feature, 8pin and 6pin leads are required.
Many older and even some current power supplies do not have an 8pin lead, but this is
not a problem since a 6pin to 8pin adapter will work perfectly. I know this
first hand, because I used such an adapter with the PC Power & Cooling 750W Power
Supply. If you getting a new PSU, I would recommend purchasing a PSU that has
6+2 (8 pin) PCIE leads and is 600 watt or greater.
