Introduction

NVIDIA GeForce GTX 295 is based on two GT200b cores that are produced in a 55 nm process. With the "old" 65 nm GT200 it was not possible to create such a dual card because of the higher power requirements and heat output. The basic thermal design of the card follows the one introduced with the 9800 GX2 which uses a heatsink sandwiched in between two PCBs which each have their own GPU and memory.

In order to achieve the performance target, the GeForce GTX 295 uses SLI to make both GPUs work together. However, as end user you will not notice anything of that. You just install the GTX 295, install the driver and it works - without ever mentioning SLI.
