So if you're all about speed, the ATI 6990 is the best in that department however if you want your games to look as good as they possibly can then the gtx 590 is for you.
The best computer graphics program of 2011 is Sony Vegas. This is an integrated, forward-thinking production environment designed for a new generation of creative editing.
The GeForce GTX 580 is either the best or the 2nd best graphics card
There are a wide variety of different places where one can purchase a GTX690 Graphics card. The best place to find the graphics card is at a local electronics store such as Best Buy.
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.
5870, 295 or 480
Geforce 6600 or ATI x1300 graphics card minimal
Buy a new graphics card and install it.
A graphic card. Well, you can get those at your local electronics, like at Best Buy. :)
A good graphics card for low details on games is the nvidia 8800. I reccammend you don't get this just to be safe. To get normal to high graphics get the nvidia 9400. For high to best Graphics, get the nvidia 9800. For best Graphics, get the 260, 280, 285, 275, 290, (all nvidia).
There is no 4X AGP Graphics card that has 256MB but only 128MB that's called the Nvidia Geforce4 Ti4600
Nvidia make some of the best graphics cards around. The Nvidia 550 ti is a very good card from their range.
Ok, i have a suggestion, i don't know if it's the best graphics card for that but it's really good and meant for that. It's called the 9400 GT. For the best deals on it go to tigerdirect.com.
I'd go with ATI
