I currently have a Nvidia Geforce 8600GT 1GB. With that I have ran Aion at high settings with minimal lag and FPS in the high 40s. Maxed out I ran Aion with a bit of lag in city as well as only 20 FPS outside of cities. So anything equivalent or higher is a good card. Make sure you have at least 2 GB of DDR2 RAM or better for your ram slots or you'll run into trouble with memory issues.
To play WoW Cataclysm it is recommended to have a NVIDIA GeForce FX or ATI Radeon 9500 video card or better. If you were to buy a $40 or more graphics card now you should be fine. That doesn't mean it will run with full graphics just that it will work decently.
ye the nvidia 6200 can handle Aion on Normal Settings
Minecraft should run decently on there, but it really depends on how much RAM you have and your graphics card. If you have 2GB + of RAM it should be OK and a decent graphics card would be ideal. The processor should be fine.
Aion costs $40.00 USD to create an account and then $15.00 USD per month to keep your account active. Paying for several months at a time can lower the price slightly. It's not that expensive and is worth it if you enjoy the game. But sometimes they make a raffle where you can win some AION money. This time AION and their partners Paysafecard make a competition where you can win £10. Here it is: http://www.paysafecard.com/uk/promotions/aion-promo/
both but the biggest improvement would be from the graphics card
That would be a video or graphics adaptor or simply, card.
The computer can be used to find the MB of the graphics card. The graphic card is usually mounted on the graphics card reader. The MB of the graphic card can be read by looking at the drive of the graphics card.
Why in gods name would you!!
Step 1. Find out what graphics card you have.
If its not really for gaming or entertainment, i wouldn't even spend the money on a graphics card. I would go with a low budget integrated graphics chip. But if you are only given the option of getting a graphics card, I would just go with the lest expensive one because a discrete graphics card is already going to be more than you need.
Every PC has to have either graphics embedded into the motherboard or either a a dedicated graphics card that fits into an expansion slot on the motherboard. You can buy a motherboard without graphics, but you would need to supply a graphics card to go with it.
you would connect a graphics card to this port which i believe is what you're asking
