Which vid card for a budget PC?

[thor17usa]

I am building a system for my friend and he does not want to spend a lot of money, but we want to get the most power that we can. I am looking at these two cards and want to know what would be a better choice in terms of power and future use.

SAPPHIRE RADEON 9800PRO 128M Radeon 9800PRO 128MB 256-bit DDR AGP 4X/8X Video Card - OEM

--or--
CHAINTECH SA6600 Geforce 6600 256MB 128-bit DDR AGP 4X/8X Video Card - Retail
http://www.newegg.com/Product/Product.asp?item=N82E16814145112

I noticed that one has 128bit memory and the other has 256bit memory. Does this make a difference in game performance? How much of difference will it make in Battlefield 2 for PC?

I already have most of the parts for his PC:
CHAINTECH SKT600 Socket A (Socket 462) VIA KT600 ATX AMD Motherboard - Retail (here (http://www.newegg.com/product/product.asp?item=N82E16813152040) )
AMD Sempron 2400+ 333MHz FSB Socket A Processor - Retail (here (http://www.newegg.com/product/product.asp?item=N82E16819104210) )
VIKING 512MB 184-Pin DDR SDRAM System Memory - OEM (here (http://www.newegg.com/product/product.asp?item=N82E16820141508) )

We will figure out the other parts later.

Any input is greatly appreciated.
