Should I buy the physics card or a sound card?

I am thinking of getting a new desktop for gaming. Should I get a physic card or a sound card?

Thanks for all advice in advance.

Thank you for the reply. Since my company is going to buy the PC for me, I am thinking of getting something built from Voodoo.

Currently I am thinking of an air cooled system with FX 62, dual 7900GTX, 2 Gigs ram, 150 X2 WD raptor. DVD dual layer DVD.

The company doesnt care unless I make it an issue since I am the head of the division. And the IRS in the country where I live doesn't really understand computers too well to make it an issue. Which is the reason to why Voodoo seems like a choice since they ship anywhere in the world.

Anyway as to the question of the motherboard, I too was under the impression that the ASUS motherboard could actually fit the sound card and the physisc card but apparently it does not since not with dual graphics card. The configuration section of their site won't allow me to do this either. Any thoughts on this?

Thank you very much for the reply. I knew the 7900 were large but didnt think they would take up that much space.

As for the physix card, I think I am getting the picture. It seems way too early to even bother to get it. I mean if people are experiencing a slow down in FPS rate, I am starting to wonder what is the point...... And if that's the case, I guess the sound card is a better choice since I'll see the quality difference every time I boot something up.

Anyway thank you once again. Much appreciated.

Definitely buy a sound card cuz you can use it other than just games, you know. I have the X-Fi Extreme Music and by far it's the best card I have ever owned. This card has tons of features in it. It produces high quality sound during music, movies and gaming, so you know it is a good investment as well.

The physics card on the other is good but not right now, for it just gonna slow down your system due to that it's adding more objects and effects for the cpu and graphics card to work on and it's using a slow PCI bus. Besides the games that supports this physics card is very dissappointing (Ghost Recon: Advance Warfighter) and performs so bad as many have tested it and having 15-20 fps using the physics card. So that said the physics card is not a good idea right now.

I highly recommend the X-Fi Extreme Music for you. You won't be dissappointed with it.

You might just try and look at some other vendors. Some are offering the new Nvidia 7950 graphics set-up. Here's Tom's Review.

With these cards you won't eat up all your PCI slots and can get a X-fi and a Physx card on your employers dime. If you look at the reviews these 7950's are fast. Here's a link depending on where you are located. Maybe you can have your cake and eat it too.
