Card Comparison

[Matt]

How would you arange these in order of performance:

6600gt 256mb
6600gt 128mb
7600gs 256b

what im asking is, how does the 7600gs compare against its older brethrin

First the 6600gt 128mb, then the 6600gt 256mb and last the 7600gs 256b.
The 7600GS is only a little faster than the 6600GT. With a little overclock and a capable system, the GT can equal or outrun a GS.

Isn't the 7600GS a 12-pipe card? Surely that would provide a much better performance increase over just speed.

Yes it is. But the even though it is a newer, more efficient core, it still uses DDR2 memory onboard at 800Mhz and has a lower clockspeed (400-450) compared to the 6600GT(500). In most cases, I've seen the 7600GS pull ahead by 4-8 FPS. Which is why a little overclock can equal it.
SLI is not much different. An increase of a mere 8-15 FPS.
