Each card has stood out in the area that it was designed for. Older benchmarks written for DX 8 clearly like the Ti-4600 better than the newer FX card and in spite of the power behind it, the Ti-4600 is simply not capable of surpassing the 5600 FX in the newer technology written into DX 9. The only exception to that is with the Splinter Cell test which was written with DX 8 and released with DX 9. The game engine benefits from the power increase but eye candy in game is not as nice as the 5600 produces. So our finally decision is that for those of you who are into the newest games it is definitely worth the upgrade for the graphics alone.
