Hello, I am having a problem with the performance of my recently purchased hd 4850 . Spent the last couple days trying to fix it but no luck yet. On October 8, 2008 i replaced my 8600gt with the sapphire hd 4850. Installing the card seemed to be no problem: deleted nvidia display drivers, turned off power, swapped out cards, attached the extra power cable to card, turned on, windows detected new hardware and installed card, then I installed the newest catalyst drivers. Restarted PC after everything was installed, I open counter-strike: source and do a video stress test to find that I am getting the same fps maybe less than i was on my 8600gt. Go into a server and getting same performance as my 8600gt. Did the same thing with crysis. I've seen videos of people running this card smoothly on very high quality in crysis. Mine is pretty laggy on high and doesn't even give me the option to go to very high settings.
So i guess my question is what do I need to do to get the right performance out of this card?
I didn't change anything in my system bios yet, is there anything i should change?
My motherboard is an, "msi k9n neo-f v3".

It has 1 pci-e x16 1.0 slot. (all the specs in that link) I have heard that having a 2.0 slot does not give you a great performance boost, about 1-2% on the 4850. So it shouldn't be a pci-e slot problem. My motherboard isnt very new so mabye i do need a new motherboard for this new card?
I doubt that its a power problem. Right before i put in the card i installed a new 600w power supply that works great. 600w is plenty enough to supply power to this card. And like I said, i did plug in the extra power adapter into the back of the card. Haven't had any power error messages. I can manually increase the power using the ati_rbe program if needed. Do i need to configure my motherboard to give it more power since i just installed from a 480w to 600w?
Card is not overheating, its at 40 degrees celsius right now and in game is around 50.
Also i am running Windows XP home sp3, that may have something to do with it but i dont think so.
Help would be veryyy much appreciated, i really have no idea what to do. Havent seen people with the same issue as me.
Thanks in advance
