I'm just saying, I've helped several people this week with budget builds in about the same price range, and they just don't understand that an i5 + 6770 is going to suck compared to an i3 + 560Ti/6950
+1 - I generally wouldn't recommend an i5 to anyone who's not looking to buy at minimum a 6950/GTX 560Ti. Maybe 6870 at a stretch but as you say, the performance from an i3 with a graphics card a few tiers higher, is going to provide much better performance in games as they stand currently.
I regret pumping so much into my i5-2500k, -v PRO mobo and GTX 560Ti, especially since I don't even find myself gaming on it any more. A nice i3 build like the OP posted would have saved my wallet a little and been more than substantial
