Nice thread Slava. Don't pay attention to the people that don't believe the increase in performance, they just dont have a damn clue what they are talking about.
Owning an X-Fi, I can honestly say the performance increase you talk of is almost non existent. Maybe if you were playing at 640x480 on a low graphics quality, then you would notice a difference in framerate, but anything higher makes it almost nonexistent. I'm not saying a soundcard is worthless; I own an X-FI, however I cannot justify the purchase with performance increases.
Okay, guys... One last time: It is not about how immediately noticeable the boost is. It is about % of total perfromance. All else equal, would you rather have 100% or 105%?
By way of analogy:
1. Do you see a major difference between driving at 50 mph versus 55 mph (50 vs. 55 is a 10% speed increase)? I am sure you do not, especially if you are driving on an empty street. But enter a highway where (for the sake of discussion) every single car is going at 50 mph while you are doing a steady 55 mph. Major difference? No, but you
are passing everyone. Heck, you will be passing everyone even if you do 51 vs their 50.
2. Not long ago there was an automotive discussion on this forum. Some people (myself included) were wondering what's the big deal about a 500 Hp HEMI engine. Well, 160 Hp or 500 Hp does not make a difference (except in the fuel consumption department) in day-to-day driving when you spend 50% of the time in traffic jams. But, for example, if you could afford to have a turbo car instead of the non-turbo version of the same car which one would you prefer? Or the same non-turbo car with some performance options installed?
Point is that evey little bit helps. And PC performance enhancements
add up
If you are using a top of the line Core 2 Duo CPU, it is so powerful that you will likely notice no difference in your PC performance regardless of the type of sound card you are using. But, most people have average machines; and those who come to this forum trying to figure out simple and budget sensitive ways of prolonging lives of their below average machines should be aware of performance benefits of using dedicated sound cards. What else can I say?
