Nvidia nForce 650i SLI is a good option.Why?
Obviously, the Nvidia nForce 650i SLI is easily the smartest option for those that are seeking SLI (Scalable Link Interface )support on the Core 2 Duo platform without all the extravagant options out of all the new nForce 6-series chipsets
In terms of performance, the 650i SLI is just as good as the 680i SLI, so one may wonder why does the P5N-E SLI cost just $140 while the competing ASUS 680i SLI board costs a neck-breaking$270?
For your information:
Scalable Link Interface (SLI) is a brand name for a multi-GPU (Graphic Processung Unit) technology developed by NVIDIA for linking multiple video cards together to produce a single output, therefore increasing the processing power available for graphics.
