New beta drivers support two new and up coming cards from nVIDIA. The GTX 590 will probably have two GF110 GPUs accompanied with 3GB of GDDR5 memory, while the GTX 550 Ti is based on the GF116 GPU. Interested in the specs? How does 40 TMUs, 240 CUDA Cores and 1GB of GDDR5 memory on a 128-bit interface sound clocked around 870/1740/4000MHz (GPU/CUDA Cores/Memory)? Sounds too good to be true you say? Well it should meet certain performance levels if it wants to fill the shoes of the 768MB variant of the GTX 460. The money conscious gamers should keep an eye on this piece of hardware.
