Can anyone recommend a good $30-$60 video card that I can get at a store or ebay?
And I'm just going to get a new sound card. I might want 5.1 after all.
As far as a MAME cab goes, any "newer" ATI or Nvidia GFX card will do. MAME uses the CPU to do all of the GFX work (except output to the screen, of course) So I am sure finding a good 30 dollar card wont be hard. You dont need all of the 3D this and that on the card for MAME... (Even if the games you run are 3D even)
As per the sound card, if this is a MAME cab, why do you need 5.1? I havent heard of many/any arcade games that take use of 5.1. Actually, I think the highest I have seen on ANY arcade game before c.2000 is just stereo... If you are going to be making a Jukebox, I could see 5.1, but in a cab, there is no point.. (If you are making a Juke, fire a PM to Uncle T, im sure he has some good advice on soundcards as he seems to be the most active Juke resident here right now...)
