Switching from 7100 GS , and benchmark frustration

Hi , i have 7100 GS , it didn't run the game

dreamfall the longest journey , the gfx card is 512 , and the pixel shader is 3 , so i want to buy
a

8600 GS
8600 G????

what does the GS GTO .... etc mean ?

actually i'm from jordan , and the 7100 GS was bought by 110 Dollars , and the 8600 worths 150 dollars , is the diiference huge between them ?

now , i want to buy a new graphics card , 8XXX serise , what does each number denote ?

the application

benchmark2006 showed 2 to 3 FPS , what is my problem

pc :-

ram = 2048 DDR2
cpu = 3600 DualCore

please help me , it will be too apreciated .

the difference would be night and day, anything that had a 7 in its name should be avoided. however, what price do the 3 series by ati go for.

the 8 is the family name, the second number is the place it holds within the range with the latter letters, denoting variations within the range.

if the 3and 4th number are 50 then usually that means a newer revision or it did witrh the last generation.

also, your english is fine.

thanks , i dont know the ati price sorry , so is the difference too huge between 8600 GS and 8600 GTS ?

what pixel shader have it to be ? , would it run 3dmark 2006 with normal settinges , fastly <more than 20 FPS> , thaks again .

thanks , one last thing , is 8600 GS capable of running most games these days , like COD4 , and the PS2 emulator <legal , becuase i have the consol , but i want to see can my computer run the emu better with the new gfx card>

thanks too much .

it will, trust me, i own one.

To 3DGURU, check how much the ATI HD 3850 costs over there, as it will be MUCH better than either the 8600GT or 8600GTS. If you can afford it, then get it, as it is the best in its price range.
