    and for the whole sound card thing..yes X-fi has about 15% quality increase over the Audigy and has higher SNR (actualy it is as good as a studio quality recording device) and has about 24 times more processing power than the Audigy (meaning it can process a hell of a lot more audio paths simultaniousely) and it DOES increase gaming performace quite a bit than using a onboard Sound card...and yes you will need a very good audio system hear the difference... i got a Altec Lansing Mx5021 THX and it make a huge difference when i plug the x-fi in (MX5021 is a superb product if u have one u will agree with me)..my recommendation is if u have 100 bucks to spare buy a x-fi (dont buy the x-fi extream Audio it does not have the EMU20K1 core it has the CA0106-WBTLF from Audigy) its worth it...(that is if u already have a great CPU and a Video Card if u dont, spend ur money on them before going for a x-fi)

    Yes the MX5021 is awesome.....I saw the thing at unity......They had a display......Btw Xtreme Audio still sounds better than Audigy 2....Dont know about Audigy 4 ....but the tone n the vocals are better on the Xtreme Audio......

    aww yes u must be right i havent tested one yet but im sure Xtreme Audio have a Audigy 4 DSP so it must sound a wee bit better than a Audigy 2....

    well well look whos talking, the facts are:
    * Core 2 CPUs are not made to go beyond 3.2 GHZ (over this limit it will reduce the life span of the CPU by electron leaking in transister levels)

    * 160 bucks is a lot u can buy a Radeon 3850 with that kinda money (the best card for that money range) and it will make ur games run faster :P

    * i was not wrong here : "E 6600 mul 9 OC on a 800MHz = 9x400 = 3.6 GHz (almost the limit of a air cooled Core 2 with a G2 revision G0 go a bit higher)
    E 6420 mul 8 OC on a 800MHz = 8x400 (corrected from 333) = ~3.0GHz"

    u simply confused the 800MHz (what i meant was the speed of the RAM not the FSB) as the FSB, yes i know its quad pumped, thats why i said 9*400(1600/4 = 400:P 1:1 ratio with the DDR2 ram as u know DDR2 is double pumped means its base freq is 400MHz) and in case u dont know how to multiply 9*400 = 3600 Mathematicaly prooven :P 400
    9 *0 = 0
    9*0 = 0
    9*4 = 36
    ------------
    3600
    ========
    "And just for the record
    E6600 stock is 9*266=2400MHz
    E6420 stock is 8*266=2130MHz
    "

    and ur point would be what ???
    i was not talking about the stock speeds of these CPU's

    anyway sorry for the late reply
    AFAIK, higher clock speed doesn't lower the life span of a CPU because of electron leaking. It does, however, lower the lifespan because higher the clock speed, higher the heat generation, and higher the operating temperature if all the other factors are kept constant. HIGHER THE OPERATING TEMPERATURE, LOWER THE LIFE SPAN. That's the rule.

    Transistor leak will occur at higher "voltages" and higher "tempreatures", but this is not the biggest problem these days. "Electron migration" is a bigger deal, because it might happen at as low as 1.4V on a 45nm CPU. You should never go over 1.5V with a 65nm CPU, regardless of whether you are using a phase change or peltier cooling setups and are running at lower than 0C. Electron migration is the phenomena of bursting the interconnects when a denser flow of electrons flow through the "wires".

    you are correct anusha but Higher frequency means high temps and high voltage...thus reducing the life of the CPU...and im sure u know that there is a technical limit to a CPU frequency that does not violate the stability,life span, thermal yeild standards...even if u maintain the temp there are other factors that will reduce the life of a CPU if it goes beyond the frequency that it was designed to run at

    There is a limit to the clock speed, and it is dependant on the following factors.

    1. Temperature = Higher the temperature, more the transistor leak is, and the correct clock levels (high and low) cannot to be achieved.

    2. Voltage = There is a defined voltage level for high/low values of a clock. For example, 5V for high and 0V low maybe theoretical, but actually the circuits identify high as 3.3V+ and low as 1.5V-. (These maybe not be the values used in a CPU) And There is something called a rise time, as in the clocks do not rise really sharply...They increase kinda exponentially (like a charging capacitor), not as a brick wall. So if the high/low values cannot be reached within the half cycle, things go haywire. This is the worst case, you always have to keep a safety zone so that it never happens. And also the clock shown on the pic is exxagerated to make you folks understand it.

    3. Process tech: 65nm or 45nm etc. I'm not entirely sure how this works though. Probably has something to do with tunneling (as in quantum physics; 25nm tech is supposed to give phenomenal yields...as I read somewhere) This is also the major factor in making higher clocked CPUs without endangering the components within the CPU.

    cool there u go..ohh i have seen this chart before..ur correct...as the fabircation process gets smaller quantum level physics comes in to play, yes its called quantum tunneling.

    Well, I came up with the graph tbh :D

    So when applying a higher voltage, the risetime can be lowered (slightly of course)

    Where did you get that info? Audigy 4 and which version of Audigy 4?

    EDIT=Xtreme Audio has CA0106 as u mentioned and it is used in Audigy SE, Audigy 2SE,Live 24bit etc...Audigy 4 Uses a different chip(Cant be sure what it is) which has hardware capabilities.....The Pro uses the Same Audigy 2 ZS chip with better DACs actually four CS4398 DACs....

    You are telling that I was good yesterday is bcoz i didn't tell nything to you and thats bcoz you told nothing to me.

    Knowledge is accessible easily in this 21st century if you have Internet, You also have learn many bcoz of the net . Yes we do copy paste more often but not to boast the knowledge like you but to give others some knowledge. what you do is copy paste some news and wait till another member post in your thread and start arguing with him, or post some damn showoff thing, quoting a thread starter's post.
    (brainy ppl never show off their knowledge or criticize others)

    I felt a good difference(well I dont know if its my ears are bad)going from AC97 audio to Creative SB audigy SE ,both are onboard.(The creative one is same as SB 2 ZS external)It felt great with EAX,bass boost and lots of things.But Unfortunately I feel like all the SBs are same in quality like.

    This was posted by our dear friend zCexVe on TPU forums...So zCexVe why do you post something like this just to prove me wrong?
    zCexVe said:
    Virtually its the same quality but the few things like CPU usage are different considering the OB and separate card.
    zCexVe said:
    Now since we have great speeds and OB sound is so great,Actually sound department doesnt need to be a addon.
    zCexVe said:
    But with the addons like almost dieing EAX,CMSS 3D I accept you cant beat a normal onboard.

    EDIT=If your OB Audigy was so great think of a separate Audigy with real Audigy chip........
