Hello, all. I'm new here. I'm old. I'm learning new stuff-- slowly. I have older than dirt rig, i5-3470. I have limited means. I want to learn about post processing and to probably use Topaz Gigapixel. I have Photoshop CS5 which runs acceptably, Gigapixel does not. I think the processing is too complex and the files too big.Mostly, gaming is discussed here, but I don't understand the gaming needs vs what I want to do. There is probably not a simple explanation so I won't ask. Instead, to be direct, is there a meaningful upgrade w/i the limits of my old system and 1155 socket? Thanks in advance for your help. J
