Yes, things have changed lately as Intel and AMD fight to put more power into their chips while trying making them cooler.
Have you seen the new games cranked all the way up to max? If so, then you are the best judge if it’s worth it. Personally, if I were a gamer then I would want the latest and greatest and would sell my old stuff on e-bay to recoup come costs. Oh, and AMD is better for games overall – in fact, AMD wins 95% of the time in benchmarks (I noticed you were leaning toward Intel).
By summer there will be new video cards out which means the current top grade ones will be coming down to reasonable prices.
