What is the cost of 1 Gb Graphic card?  

hey, you can check the http://www.priceindia.in it gives you a very good comparison and technical detail on what all your system and games require. I personally like the nvidia cards, they have great resolution...

It depends up it speed and brand name. For 1Gb graphic card of 256bits has higher price than 1Gc card of 128 bits.

recently external graphics card has been launched

Prices vary by country, computer, operating system, and what you need the card to do. Check out your computer manaufacture's website. They often have free driver downloads to help inhance the pre-existing grafics card you have.

However, if it's online games you're looking for just search online games in your favorite search engine and see what results you get.

Tigerdirect.com is a great place to find all of you computer parts and accessories. they also have graphics cards for pretty cheap a 1 gig can range from 100-250 depending on the brand. but they are pretty good for gaming. espicially graphic games.

i think a 1 gb graphic card bought single you can spend around 150-200$ if i don't remember bad!!I think for example an nvidia gtx 1gb costs like that...

If you are from India, then the Nvidia 9400 GT (1 Gb version) will cost you around Rs. 5000.But it will vary from state to state.You can also go for the 8800 GT, which is much more preferred than the 9400 GT.And if you want costlier ones, then there are options like the 9600 GTX and the 9800 GTX.But these will create a deeper hole in your pocket.

Depends on the graphics card.. I have seen some that I have never heard of which seem rather "cheap" but no one says that they would be good for gaming.

There are more things that you need to take into consideration than just the memory it has.. like what kind of slot it uses or what pixel shader it supports or how fast it is.. etc...

Sorry, I'm not the best one when it comes to graphics cards but I just thought that I should mention this..

256kb graphic is not enough for your computer, 1gb graphic would be best option for your pc. I suggest you to check prices at http://www.xprice.com

it depends on the chipset of the graphics card. older chipsets like the nvidia 210 will be cheaper but newer chipsets will of course be more expensive. I always recommend nvidia cards, and also you can look at a comparison chart at http://www.nvidia.com/obj...
