Spend how you want, but the Ultra will not be $60-100 faster. An Ultra is ecentially just an overclocked GeForce 2 GTS chip with 4 ns ram. A Pro is a GeForce 2 GTS chip with 5 ns ram. Gainward supplies their Pro with 4.5 ns ram. The Ultra's only advantage is it's 250 MHz clock speed and it's 460MHz ram speed. With over clocking you could get the Ultra's ram speed up some, and even the GPU, but the GPU is still the same as what is in the Pro. There is always the chance of getting Pro than can achieve the same core speed of an Ultra. The Ultra's primary advantage is its 4 ns ram wich allows for higher rams speeds, and ultimately a higher bandwidth.
