There is zero reason at the moment to spend the extra $100 for hyperthreading for an i7 for gaming - DirectX 12 may change that, but it's been a year now and we've yet to see any appreciable DX12 launches with big gains in that area. Would be a much better idea to get an i5 and a better graphics card at the moment. SSD for operating system is definitely a must.
As has been echoed for several months now, anyone who buys a system right now is going to regret it when a generational leap in graphics architecture is only a month away with Pascal/Polaris (early June availability is almost a certainty at this point).
