How to Select a Sound Card
In today’s hi-tech world one really gets overwhelmed with the wide variety of sound cards available in the market. The most important point to consider before buying any sound card is to consider its intended usage. If you just need a regular sound, then either go for a simple cheap model or rely on the motherboard’s on-board sound. If you really require fantastic surround sound or better speaker connectivity, then you will probably need a dedicated sound card.
A sound card’s cost can vary from anywhere around £5 to £125, depending on the features. One should then analyse which type of sound card fits in your allocated budget and what features it offers in terms of surround sound etc. Some sound cards, such as the Creative Labs Sound Blaster X-Fi Elite Pro, are even capable of providing 7.1 surround support. You should also check to see if you have special needs to cater for. If you are into professional music or track recording, then you will need to consider a multi channel sound card.
While selecting any sound card you should always ensure that you have an equally powerful CPU to go with it. There is no point in installing the latest high-end sound card with EAX and 5.1 surround sound into an old Pentium 3 computer. And last but not the least, you should also check on what software comes bundled with the sound card package. This will always save you a lot of money, especially if the sound card package includes that special software that you have always longed for.
To conclude, sound cards are a gateway for experiencing true multimedia. Make sure you do your homework well and consider all your audio needs before narrowing down on any sound card.

You could not get that more wrong
Hardware processing of EAX makes even more sense in Pentium 3 PC - as you want to save precious CPU cycles
Besides - almost all Sound Blaster cards are capable of delivering 7.1 - even these $30 cards. With Elite Pro you pay for versatile connectivity options (optical, coaxial inputs, outputs, multiple analog inputs etc) and better components etcetera.
