The number one provider of motherboard chipsets on the AMD platform is NVIDIA with 62% of the AMD motherboard market, according to Mercury Research. This is true today despite the fact that their main competitor, ATI was recently bought by AMD. The recent launch of the nForce 680a along with AMD's QuadFX only cements this standing in the AMD market, as the Quad SLI+2 FX-70 combination provides wonderful performance rivaling that of the Intel QuadCore QX6700 CPUs. It is interesting to see where the relationship between NVIDIA and AMD will go moving forward, as they are competitors in the graphics card market and motherboard market. For the everyday user, the single CPU AM2 platform is still the most available and usable AMD platform, with the new FX-70 series requiring a new Socket and therefore not compatible with the earlier AM2 motherboards. The best chipset for the AM2 platform for SLI video cards is the nForce 590 SLI chipset bar none, as it offers the performance and features that you expect from a high-end chipset. Today I'm reviewing the Biostar TForce 590 SLI board.
