If you want to get the cheapest, most stable video card for an audio app., get at least 32MB 4x AGP,I, and most people I know, use the old reliable Matrox 450, or the G550. They are not for gamers, or have 3D, but I have been using this gem in my 3rd computer now. Thats what I like. STABILITY.
Sure, there are better ones out there, but I do a lot of live work, so stability is paramount.
Thank for your advise James, i also like stability but i blow off my budget already and i wonder if i could get away with the Matrox millennium G450 16MB 4X AGP Dual-head, i can get those for $15. Do you have any friend who still use those?
