I went with the GTX770 on my new i7-4770 system.
On my older system I installed a Corsair H110 on my i7-930 (long backstory, but it was either that or spend another $50 for another cooler, so might as well use the H110 since I can't return it). I removed the cooling block to replace the stock TIM with some MX-4.
Since then, my system wouldn't resume from sleep and the power supply would do this weird cycling thing where it powered on then off twice before the system would boot, and I'd get an error that the overclock settings failed and needed to be reapplied in the BIOS. I cleaned off and reapplied the TIM and tried some other things, same problem. Then I checked the pins on the socket on the motherboard and found that some of the pins were bent and touching each other. I used a piece of index card and a small screwdriver to bend the pins back into place (a pain in the ass, need a magnifying glass and a very small screwdriver). Now it boots normally and everything works fine. Cooling performance of the H110 on the i7-930 is nothing special, worse than the Xigmatek Dark Knight II I had on there before. It's also not much quieter since you have two fans on the radiator instead of the one fan on the HSF.
Lesson is to be careful when installing/removing the CPU from the socket, as you can easily bend the pins and ruin the motherboard or get weird behavior from your PC.
