At last we can see just how much penalty 4x transparency SSAA incur on both cards. Looks like performance drops to around 1/3 of normal performance levels. So, it's even worse than what the numbers on the screenshots showed. We can also see that even 4x transparency MSAA incurs a slightly higher penalty than normal 4x AA. The GeForce 7800GTX fares slightly better than the GeForce 7800GT, but in all honesty, since we're not really achieving much in anti aliasing, it's better off to choose normal 4x AA than forcing 4x transparency MSAA.

	GeForce 7800GT
	Default	4x AA 16x AF	Alpha MSAA	Alpha SSAA
<30 fps	0	1	1	63
30-45 fps	1	0	0	0
45-60 fps	11	40	60	0
60-90 fps	50	22	2	0
90-120 fps	1	0	0	0

	GeForce 7800GTX
	Default	4x AA 16x AF	Alpha MSAA	Alpha SSAA
<30 fps	0	1	1	63
30-45 fps	1	0	0	0
45-60 fps	11	15	19	0
60-90 fps	50	47	43	0
90-120 fps	1	0	0	0

Here we can see more clearly the extra pipeline and processing power of the GeForce 7800GTX really helps it to offer a higher frame rate than the GeForce 7800GT. You only lose performance on peaks with the GeForce 7800GTX. Of course, just like what the numbers show, even a single GeForce 7800GTX is unable to cope with the demands of 4x transparency SSAA.
