I've been reading a bit lately and it seems like the Intel i5 2500 is the way to go for the CPU, and that for gaming at least it's just as good as the i7? Something about games not being able to use the 4 virtual threads on the i7?
That is certainly a good way to jump right in but a few points to consider:
1. For gaming, the i5-2500K will perform just as well as the i7-2600K, which could mean savings of ~$100.
2. If you are getting an unlock CPU (especially an i5-2500K or i7-2600K), there is no "maybe" for overclocking - it's just too easy to milk more performance out of these chips.
3. Going down the overclocking route, you'd want an aftermarket CPU cooler. Popular choices such as the Cooler Master Hyper 212 EVO or Noctua NH-D14 won't play well with the tall heatsinks of the Corsair RAM in that combo.
4. Or, you can stick with the combo and that graphics card and pick up a closed water-cooling unit from Corsair.
