In our previous article, we were deeply impressed by the GeForce GTX 460 running in SLI. These two graphics cards leave the higher-end GTX 480 in the dust. This is good news for end users, of course, because we are provided with the chance to experience high-end performance without having to pay just as much.

NVIDIA then released an even more affordable series of GPU, the GeForce GTS 450, which offers remarkable performance for its price. However, the performance is still insufficient to run games with acceptable frame rates at higher resolutions such as 1920×1080. Adding another card for nearly double the processing power is one logical solution for this problem. We saw more than 90% performance improvement with the GTX 460 in SLI, so we have one question in mind: will two GTS 450 cards perform just as good?

SLI Configuration

To run two GeForce cards in SLI mode, you will need a pair of identical graphics card. Be sure that your motherboard provides at least two PCIe x16 slots and officially supports SLI. For Intel platform, SLI support is provided by the Intel Series 5 chipsets, while AMD users can use nForce based motherboards.
