I wasn't really concidering an upgrade up until I got offered a killer deal. I would basically be paying $25 out of my pocket to trade up to HD4870. Just wondering if it's worth it? I play games at 1680x1050; mostly COD4. I do plan on checking Far Cry 2 out and maybe beating some of the older shooters. I want to play through Crysis, but my GTX only gave me about 25-35 fps on custom config, which is something I could not deal with. From reading the reviews, It looks as if though the HD4870 will ovver about 35% performance incrase in Crysis and 45% increase in COD4 over 8800GTX? THoughts?
