Trust me it is so worth the wait. Also if you're going to use the PC for just gaming , a 3770 will be a waste of money. Get an i5 3570 because the difference between the i5 and the i7 is HT (Hyper-Threading), this has
zero performance difference. This saves you 120$ for a better graphics card.
Also if you're going to go for the new architecture don't use the old chipset. Get the Asrock Z77 Pro3 from ROG (Costs 200$) The reason to buy a Z77 chipset is that it is optimized to be used with new Ivy Bridge CPU architecture. It has 1600MHz memory controller and PCI-E 3.0. Paying that much money on an old chipset is just, stupid.
So that's 360$ for the CPU 200$ for the motherboard, 60$ for 8GB of ram, and as for the graphics card , get the HD 7870 from PCandParts. The HD 7870 is as fast as the 580, can run on a 500W PSU and run VERY cool.
