You're looking to replace your i5 2400 with a lower-cost Intel CPU that supports the 1155 socket. You're concerned about whether the I7-3770 will cause a bottleneck for your GPU. Make sure to check compatibility and performance expectations before making the switch.
They both appeared during a similar time period (I recall Maxell released Haswell), which means it won’t cause any delays.
The i7-2600 could be an attractive choice if you locate it at a very low price, offering performance comparable to the 3770.
