Wait a sec...
In what universe is the x1550 a slower card?
The x600, even the XT model, operates the core at 500 Mhz and DDR1 @ 740.
The x1550, in the meantime, is a newer generation prcessor with a core speed of 600 Mhz running twice as much RAM, DDR2 @ 800 Mhz.
The x600 runs shader model 2.0b, while the x1550 is shader model 3.0.
Here is a link that has the x1550 running HL2 over 80 FPS:

And this benchmark shows the x600 at no more than 50 FPS:

So, explain to me how the x1550 is a slower card than the x600 please?
