By upgrading to a Sandy or Ivy Bridge i5, you'll get around 10-20% performance per clock and 10-15% higher clocks, which comes out to an overall 20-40% improvement.
If I had a 760 I'd probably hold out for another generation.
Let's see..
CPU: i5-750 @4GHz, faster than a stock clocked Ivy Bridge i5. Only an i5-3570K OC'd to 4GHz+ would be an upgrade. Given your budget, there's nothing to upgrade here, wait for Haswell in 2013.
RAM: 8GB DDR3, presumably that's enough for your purposes.
SSD: You already have one.
Case: Nice.
PSU: Unknown but presumably decent enough.
That leaves the GPU. By selling your 6770, you could afford a 7850 2GB which would double your framerates, nearly triple after OC. But if you find your framerates decent enough in the games you play, no point in upgrading the GPU yet.
