I'm putting this together for anyone interested in upgrading their GPUs (video cards) and if they have any concerns of what will work in their system. This is gonna run a little long but it may serve as a reference point to those of you who may be timid at looking under the hood of your PC.
Disclaimer: I am not a professional!
I'm just a guy who learned how to build a PC about 7 years ago and have been hook on it ever since. I also love FPS and even though I'm not as good as I wish I was, I love to play the lateset and greatest with HIGH SETTINGS!
SO here we go.
One of the first things to consider is the wattage on your power supply. This could be found in one of several locations. The most common is a label on the PSU itself. It will list the maximim wattage that it will supply as well as other technical info. If you have a store bought system Dell, Sony, eMachine, etc. the information would be listed in the owner manual under specifivations. Another option is google. Search for your PC by Manufacturer, make and model and you should find the tech data or a PDF of your manual there.
Most mid range to high end cards require 400 watts of power or better. Although 400 is recommended a PSU of 350 to 375 should handle most mid range cards. If your looking for a 2 card solution then the value increases to about 600 watts. More cards equal more juice. I'm including a link to a power requirement calculator here (http://www.antec.outervision.com/) to give you an idea of how much power your current system uses and if a power supply unit upgrade may be necessary.
Asumming that you dont need to upgrade your PSU the next question is the availability of an expansion slot for the card to go into. The most common types are PCI and those range from PCI, PCI Express, PCIEX x1/x4/x8/x16 which come in variants followed by 1.0/2.0/3.0. Not sure about 3.0 but 1 and 2 cards and boards have no compatability issues. There is also the Ancient AGP x1/x4/x8 which may be in your pc if its 4 years old or older.

PCI types vary in name and size this image shows:

This will give you an idea on size comparison to a PCI slot which I would argue that 99.999999998% of store bought PCs have.
On to the next thing and back a bit to that PSU. Even for whats considered a low end card now a days a direct 12 volt connection to the power supply is necessary. I wont go into too much detail but you should see a +12volt rail or something similar on the PSU label, this is the power to your vid card. Most card connet to the PSU with a 4 or 6 pin connector. If you only have molex connectors their are adapters available to convert to what you need.

Current connection types:

More on the PSU, should you have or choose to upgrade the key is your ability to disconnect the power supply from the motherboard. Some premanufatured systems are hardwired to the board making in difficult to upgrade since the connecttions are soldered into place. I can solder pipe but I don't do electronics. So I cant help you there. There are 2 main connections to the mobo from the power supply and the are:
24 or 20+4 pin which provide power to the board for any drives, PCIEx, USB, SATA, fans, ram, etc. These are low voltage items which do not need a direct connection to the PSU.
The 20+4 looks like this:

On the board the connection look like this:
http://img.hexus.net/v2/internationalevents/computex2006/Tarinder/MotherboardB.jpg

It's the black rectangle in the lower right corner of the board.

Sometimes the 20+4 will ship and look like just a 24 pin but you should be able to "pull apart" the 4 from the 20.
The second device that requires a direct connection from the PSU is the CPU. One if not both of these are often hardwired in making a PSU upgrade more difficult on mass produced PCs. The connection to the CPU look just like the +4 and would be located next to the CPU. They aren't hard to find as they are likely the only to cables from the PSU directly to the board. The image above has an 8 pin connection for the cpu, black rectangle top right above the aluminum fins, but todays CPUs will run just fine with the +4. My set up is similar and I only have a 4 pin connected.
Back to the good stuff Once youve determined that you got the juice and what slot type you have chose your card. Ive had Nvidias and ATIs and don't particularly favor one over the other.
I have had issues with some cards from particular manufacturers but those may just have been flukes as many of my friends use cards I've sworn against and they've had no problems. The real issue for many people is $$$$$, So on that my opinion is that prce vs performance ATI takes the lead, but in raw performance Nvidia has held a slight edge most of the time. Here is an article (http://www.extremetech.com/article2/0,2845,2336249,00.asp) testing cards that are mid and high range. The choice is ultimately up to you to decide what fits your budget.
Hope this helps its not too technical and is designed for beginners. Please feel free to add to this if I have omitted anything as well as ask questions. I'm always willing to help.

That is a nice lanparty motherboard there :) it's good. I been messing with PC's since I was 13 years old here I am 35 now lol! I built my Custom PC with a ASUS M3A78 OCZ 4GB of ram. Inspire 650 Watts Powersupply to run my AMD Phenom Quad Core 9850 2.5Ghz. & my PCI-E Sapphire Toxic HD 4870 Vapor-X OC 1GB GDDR5 worth every penny :)

Just to make some of you more serious PC'ers out there start to salvate.

I have been allowed to show you the motherboard I am testing right now.
But I can not give you all the specs just the ones that will make your eyes water a little. :D:D
- Dual CPU SK 1366. :eek:
- 12 DDR3 (Each CPU 6 bar). :eek:
- 7 PCI-Express 2.0 - Support 4 way SLI. :eek::eek:
- SATA 3. :eek:
- USB 3.0 :eek:
- NVidia nForce 200. :eek:
- 8-phase digital PWM :eek:

This is the board I was running 2 Quadro FX5800 Nvidia cards on.
The ram slots all have 4gb sticks
As for the CPU's sorry I am not allowed to say but let me just tell you........
I was running Battlefield Bad Company 2 at MAX spec at over 1000 frames a second.

And here is the picture of said board. sorry I had to black out some parts!!!!



Also as a side line notes:
Not all Graphics cards need extra power.
Some of the newer boards like the one pictured below give power to the cards through the motherboard.

Sorry No wonder they said I could show it off now lol!!!!!!!! :rolleyes:

But the price tag is a little strange as I was told it would be just £200 no more than $300-400 :D:D

Not $600+ like that site says lol!!!!!! :eek:

The worst part is I have to give it back soon so they can do a de-construction of the board after I have had it. I turned it on one day and then I turned it off 15 weeks later LOL!!!!!!! :eek::eek:

My motherboard has a couple big brown slots and a couple smaller white ones . . . .

what kind of video card should I get ?

Thanks. I just update my psu, and graphics card to run bf2. Help like this is what I read up on to help me get ready update my pc. I just wish this was post sooner =). I got a new 400watt psu, a geforce 8400gs graphic card. Just now I have to get a better CPU.

I have an old 8600GTS 512mb onboard It's a spare.........

Stupid peps at AMD gave me a xfire board to test I can only put 1 graphics card in it as I have no ATI cards LOL!!!!!!

now Kil for your question

Like the PCI Express 16x above the 1x slot uses exactly the same system but only has a single lane of serial data transfer. These slots are used for expansion cards that do not require the same amount of data transfer that a graphics card requires. You will usually find components such as tv tuners, network cards and sound cards make use of the PCI Express 1x slot.

Also on some of the largest graphics cards they slot into both the PCI Express 16x and the 1x slot.
This is how the larger cards get their power.

As for the brown connectors! they usually dictate that they are not PCI-E but they are infact AGP (older and much CR@PIER style of graphics control) LOL!!!!!

When you are ready if you need help ask. There are plenty of folks here who can help with hardware as some that do well with software. Post and you'll hear from someone in a day or less usually.

Sorry - I'm confused here . . . . .

Here's a picture of my mainboard - can someone tell me where the video card would go ?

I'm no expert, especially on commodores, but i would guess that little raised green square is your integrated card. That whole board looks to be almost the size of todays after-market cards. lol

It's a C64 hahahahahaha it's only got 64K of memory LOL!!!!!!! not even 1mb worth I would never take my C64 to bits it's worth too much in it's box still looking nice and new lol!!!!!! I got it for £2.50, the other day another dealer tried to get me to sell it to him for £75 now that's what I call profit. But it's not for sale lol!!!

The 12 pin connector is for your Cartridges.
The 6 pin connector is for the casette player / floppy drive LOL!!!!!
