I was planning to buy a radeon 9800se with 128mb. i didn't know if i should or not, my brother told me that i should use the nvidia geforce 2 mx with his gigabyte motherboard( it says k7 triton 400 series or something like that) and it should do good. Basically i don't know what's the problem. I know that my computer will be amazingly slow when i play hl2, But i want to find out if it's my video card or it's just that i should start playing games in my brother's computer.
