Well my graphics card had a 1 year warrenty I believe. Got it in april..didn't work with my asus board..got new board in may..finally got to use card with board...card burnt out in July.....contacted manufacturer two months later (earlier this month
) they send me RMA Number after I've described the problem. I send it to them and pay $6 for shipping, they sent a card back about two weeks later
Simply put, you should be able to request an RMA number and send in your old HD and they should replace it, simple as that
and yes it'd be brand NEW because my card had a much smaller heatsink and fan on it and now has heatsinks where there wasn't before lol so in my case they sent me a 'revised' version.
