I used to agree on the i5 over i7 but the tables are turning. It all depends on the game, but with BF4 as an example the HT will keep the core utilization down, temps down, and noise down as the cooler doesn't have to work nearly as hard. My 3570K has to run around 95% on large maps whereas my friends with 3770Ks run at a leisurely 55-60%. If you don't care about power draw, heat, and noise, then it probably doesn't matter.
