No, these two are separate. However, some manufacturers sell both in the same box as a package deal.
Like any hardware in a computer, a soundcard can just stop working.
Any PCI-E graphics card will work.
You should not remove any component from your graphics card setup.
Yes -- your soundcard can be used to record from virtually any source.
You will probably need a dedicated graphics card to play any newer games.
There's a special breed of cards out there that aren't afflicted by the fans whirring noise called passively cooled cards.
There are hundreds if not thousands of reviews of different types of graphics cards available online, viewing several of these is a good way to find out the basics and information on what graphics cards are most often recommended for specific purposes. A local computer technician or knowledgeable salesperson would also be able to provide information on graphics cards and answer any specific questions.
Any integrated graphics chip draws upon the system RAM. Only discrete graphics, or graphics cards, have their separate RAM supply.
There is a high probability for any monitor to work with any graphic card.
There's no significant difference -- all graphics processors will produce a varying amount of heat depending on the workload.
Any of the dual-headed Radeon 2400-2600 cards should work fine. Size the OS with what you want the machine to do, a sever is what it is, not a gaming machine.
An integrated graphic processor as oposed to a discrete graphic processor. Graphic processor is the same as a video card. Integrated video cards: Integrated video cards are built-in to the system motherboard and use the system's processor (CPU) and memory to create graphics. They're fine for applications such as word processing and email and for the Internet, but not great for gaming or other graphic-intensive applications. While integrated video cards can process some complex graphics such as 3D images, they have to share the CPU and memory with other programs. If the CPU and memory are overloaded or busy processing other information, it can really slow down the graphics. Discrete video cards: Discrete video cards turn up the performance compared to integrated video cards. They are separate, or discrete, from the motherboard and have their own processor, a specialized graphics processing unit, or GPU. They don't have to share the CPU with other programs. Discrete video cards include memory of their own, measured in megabytes (MB). Graphics memory is used by the GPU to accelerate the graphics on your monitor and make gaming, movies and other entertainment intensely realistic. In general, the more memory the graphics card has the better.
