Howdy. I'm a noob who wants to build a PC. Hopefully, I'll end up with a schweet PC and some new online buddies.

I'm trying to get a baisc education about PC parts so that I can more effectivly research my purchases. A few questions:

I recently got a BFG GeForce 7800 GS, which is an AGP card. Are there any motherboards that will allow me to use my existing card and another video card at the same time, or do I have to get a PCI video card?

I like to run two monitors. If I get a motherboard that will take two video cards, will it be able to run two monitors if I'm only using 1 video card?

I've realized that a case is more than just an empty box. Is there an online tutorial for case buying? Do I need to wait until I have my other components picked out before I shop for a case?

Thanks in advance!

You should probably read some of the Hardware aricles on howstuffworks.com before moving any further. also, you may want to check the AV Science forum for questions related to video.

Some cards believe it or not, give you more than one monitor output. Most if not all, AGP based motherboards only have 1 AGP slot. this is NOT always the case. Some newer boards have the AGP slot for compatability. This is somewhat rare however.

So do some research on those sites and get back to us. Oh BTW, be sure to look at tomshardwareguide.com for hardware reviews.

For cases, it really only matters if your motherboard will fit. The case and motherboard should both tell you what their form factor is. The most common form factor is ATX. There is also micro ATX, which is smaller. Cases that support ATX support micro ATx too, but micro ATX cases don't support ATX motherboards. You probably won't see the other form factors much for modern motherboards/cases.

Don't forget Nor underestimate BTX = Balanced Technology Extended as opposed to ATX =Advanced Technology Extended.
BTX offers improved airflow to provide better cooling, better placement of power supply, and more versitile cases and hardware configuration.

BTX is a standard created by Intel. Please see Intel Technology Magazine
http://www.intel.com/technology/magazine/c...ing/dt10031.pdf

Also http://www.formfactors.org/

IMHO BTX has been underestimated.

Thanks guys.

To clarify my motherboard question: Is there anything that will allow an AGP graphics card and a PCI graphics card to be used simultaniously? If so, is the performance comprable to using two PCI cards simulataniously.

I don't care much about having a small case, but I would like to reduce noise as much as possible. I've also always felt that heat is the most underestimated enemy of computers, and it seems like BTX is a cooler form factor. But are they making BTX motherboards?

I have some plumbing/automotive experience, and I've been entertaining the idea of going with a liquid cooled system, though I'm not sure I understand all of it's disadvantages. Would I have to get components that are designed to be liquid cooled? And if the water pump goes out while I'm away from my desk, would the whole system go?

Graphics card Stacking as I have just recently learned. Involves using and AGP card and a PCI card together. Since their two different ports you can use them simultaneously. IF your goal is to run 2 monitors you can run two from a single video card as long as it has dual video output which your 7800 GS does have. Plug one monitor into the VGA output and using the DVI adapter you can plug another into the DVI port. IF you don't have the adapter you can find one online.

Most VGA/DVI cards come with an adapter now (both of mine did).

As has been said, most of the recent middle to high end graphics cards support dual monitor setups.
But to answer your question, yes, you can run an AGP and PCI video card at the same time. They won't run in parallel to improve your 3D graphic capability as is done with PCI express cards in SLI or Crossfire, but it will output multiple displays just fine. Both cards will retain their individual performance features.

THAT answers the question that I've been trying to ask! So I need to get a SLI motherboard.

you should probly read this article if your thinking about using SLIi or CrossFire http://www.custompc.co.uk/blogs/garethogde...to-memory-loss/
