Hi Bionic, I used to use the ATI FireMV 2400 and had to replace it every 6 months. I used to run 4 (2x30 +2x21)screens and trade multipul markets so they could be on for days at a time. Keep all your warrenty details as you will need them to claim a replacement, to ATI's credit they have replaced 3 all under warrenty, the last one they didnt even want the old one back. I am currently running a 9400GT which runs 6 screens less than $500 i think. Good Trading. Cheers BM
