Whats the differance between the FireGL X2-256t and the 9800XT besides one's consumer and the other is pro, and one cost $500 and the other cost $900. They seem to be the same card, and even look exactly alike.
FireGL cards are for real time rendering.
Their Open GL Performance is enhanced, but the 9800 is better for gaming, due to it's optimizations for gaming and stuff.
For Gaming, I'd recommend the 9800
