So I got a dell optiplex 9020 off eBay the listing was for a 9020 8gig ram and for the i5 4570 . Well I got the computer and was checking it out and they sent me one with a i5 3570 not the 4570 as it was listed for. They said I could send it back but I really wanted to get this blue Iris machine up and running, so what would you do in the situation should I send it back or just take the 3570 cpu instead of the 4570 ? I’ll be running 10 to 11 camera’s at 15 fps @ 2688x1520 . I know the 4570 has better performance then the 3570 but will it be so much more performance to pack this thing up and send it back?
