The ASUS EN7900GS TOP card is based upon NVIDIA's reference design for the 7900GS. The PCB is a nice purple color, pleasing to the eye if you look at the card on a test station. The graphics chip is in the middle of the front of the PCB covered by a 17-fin fan and small heat sink. ASUS placed a picture of their Samurai with a sword on the heatsink, along with the ASUS logo. The fan also has an ASUS logo.

The memory chips on the EN7900GS TOP card are 8 HYNIX HY5RSS73225A FP-14 GDDR-3 memory chips. According to HYNIX's website, these chips are 256-bit memory chips with a rating of 1.4ns, or 700 MHz clock speed. ASUS decided to clock their implementation of the 7900GS at 700MHz, which is 1.4GHz effective. The 7900GS has a 256-bit memory interface, giving the card a memory bandwidth of 44.8GB/second (256/8 bits per bytex2 (DDR-3) x700 MHz).

PCI Express connector

The 7900GS is a PCI Express only card. Unfortunately, AGP cards have gone the way of the Dodo bird only for those with legacy systems that haven't upgraded. The 7900GS requires more power than the 75W provided by the PCI Express slot and has an auxiliary power connection. Power Supplies come with this connection as standard in most modern systems.

Computer monitors have made the transition from CRT to LCD for everyone. Most bundle systems come with a LCD monitor, even the most inexpensive ones. Modern graphics cards come equipped with two DVI-I ports to work with the DVI connections on those LCD monitors. You can use CRT monitors with the card by using DVI-I to D-Sub adapters included with the packaging of the card. Also present on the bracket is a HDTV-Out port.
