The graphics card at the top is a typical GeForce 8800 GTS while the bottom is the flagship GeForce 8800 GTX. The smaller GTS version's card length is typical of any other high-end graphics card such the GeForce 7900 GTX and isn't any longer than it. The lengthier GeForce 8800 GTX owes it extended figure to a more robust power circuitry design and is 26.5cm long. So if you're gunning for the top edition, check your chassis clearance first.

These new gems are proper dual-slot graphics cards, have dual dual-link DVI connectors with HDCP compliant outputs. Just as we expected. TV-output is still available via the 7-pin min DIN connector.

Watch out, the GeForce 8800 GTX requires a two PCIe power connectors and that's mandatory. If you don't, there's a buzzer on board it sound you out. With the card's already extended length, it's a good thing that both connectors are angled upwards. A minimum of a 450W power supply unit is recommended for this GTX version.

The slightly slower GeForce 8800 GTS brother requires a single PCIe power connector. A 400W power supply unit is recommend.

SLI is of course supported on these GeForce 8800 beasts, but the GTX variant comes with a pair of SLI gold fingers. We suppose it's for quad SLI support by means of daisy chaining multiple cards or to dedicate a third card for physics processing, but these are just educated guesses for now as NVIDIA doesn't plant to disclose them now. If you do get a pair of these cards, you can use either connector to enable SLI.

Removing the huge cooler, you'll see that it heatsink base is thick, huge and heavy with multiple thermal pads cooling various components on board. Thankfully the cooler is so silent, you can't tell if it's functioning!

The GeForce 8800 GPU, codenamed G80, is the amazing brain of this graphics card. It's huge package measuring 43mm x 43mm in dimensions and the die is hidden by an integrated heat spreader. The last we seen a heat spreader was on the NV30 and NV35, so you can take a hint of the heat output, but the cooler does a fair job and quietly at that.

The memory chip's markings are almost missing, but these are Samsung 1.1ns GDD3 memory. That's 900MHz clock rate for a net 1.8GHz in DDR speed. Not the same speed as the GDDR4 used on ATI's X1950 XTX, but the ultra-wide memory controller combined gives the GeForce 8800 GTX a whopping 86.4GB/s net bandwidth.
