Completely loaded question, try again.
Take into consideration that ATI was bought by AMD and no longer exists.
For computer graphics, at the time of this posting, nVidia has been ruling the high-end gaming realm for over a year now. With the 8800GT, GTS, GTX, and Ultra dominating the field, and the 9 series making its debut, we are still waiting for AMD to bring a competitive high-end graphics card to the mix. The HD 3870 X2 is the closest AMD has gotten so far and it still has not reached true high-end performance.
There are more than 2 manufacturers but the main ones are ATI and Nvidea
The ATI Radeon HD 6310 is a newer graphics card and better than the HD 4250
ATI Radeon HD 4250 is a better graphics accelerator than Intel's
The ATI 5470
Well it depends on the game new games Like GTA 4 need atleast 2 to 3 GB ram and a good Nvidea Graphic Card or ATI . I would suggest getting a 3 GB or 4 GB Computer with Nvidea Graphic card as its the best .
It is the same.
The ati 4200 is so much better than the gma4500m. The ati 4200 is considered one of the best integrated graphics out there. But integrated graphics will never match a dedicated graphics card in it's default state.
Yes by a long shot
The best nvidia card currently available is the 7800gtx. However by the end of the month the 7900gtx should be out.
the hd3450
the 4330 newer anyway, should be better, nvidea recomende is more marketing than fact, although I do preffer nvidia cards. Do not waste money on an old card like a 7900 gt tho, for the same price you can get a GTS 250, but wait is this for an Mac book? then sure go for the nvidia
Is the Radeon hd 3870 a 1GB Check this one out ATI Radeon HD 4650 Which is 1GB has a DirectX 10.1 Support, 320 stream processing units and AGP 8x This card works good with my Intel P4 3.20GHz But on better CPU works Perfect.
