Depends on the Graphics card with the PC
By upgrading the graphics card.
In order to know what the best graphics card a certain PC can handle we need to know the type of PC you are asking about.
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.
The graphics card will be installed into your PC,so if 2 monitors are connected they will both have the graphics.
Any Windows-compatible graphics card will work as long as the operating system is up to date and your computer's specs meet the minimum requirements.
Yes because a PC had a better graphics card than an xbox 360
You can not convert the RAM that is on the PC to RAM for your graphics card. The only way to get RAM for a graphics card is to buy one that already has RAM on it. The graphics cards that have their own RAM are normally higher end ones that cost about $50-$70 for the cheapest ones.
Yes the PC will still run, however if the motherboard does not have an onboard video port you will not have any video at all..
basically, without a graphics card your computer can operate but you wouldn't be able to see what it's doing.
It depends on your graphics card specifications and what resolution you run the game on
