The i7-3770K is one of the best gaming CPU's on the market, and the HD7790 is a medium/low gaming card.
If you want more help you'd have to be more specific:
Are you buying the graphics card only? For gaming? If so, what games?
If you didn't have that CPU and were building a new gaming system from scratch then it's not an ideal combo as the i5-4670K would be cheaper and the price difference would buy a much better graphics card.

First of all, you might not see much advantage in many games so overall a better GRAPHICS CARD is likely to give you more performance. Here's an example:
http://www.overclockersclub.com/reviews/intel_core_i3_2120/8.htm
"In Aliens vs. Predator, the i3 2120 is more than capable of delivering the same frame rates as the quad-core 2500K."
You are, on average, probably better off to replace your graphics card instead with this R9-270X for the same price as the CPU I recommend below:
http://pcpartpicker.com/part/sapphire-video-card-112170120g
Socket 1155 4-core CPU's:
Your motherboard isn't designed for overclocking so no point in buying a "K" series. Your best choices are:
a) i5-3570, or
http://pcpartpicker.com/part/intel-cpu-bx80637i53570
b) i7-3770
The i7 won't make much difference in most games and costs $75 more ($285). The main advantage is it can convert video about 30% faster assuming all threads are utilized such as in Handbrake at most default settings.
My advice is the i5-3570.

(I just realize there's a small chance you meant HD7970, and NOT the HD7790. If you meant the HD7970 you should be getting the i5-3570. If not, and it's really the HD7790 ignore this.)
Better explanation:
In gaming, you are usually bottlenecked by either the CPU or the Graphics Card. This VARIES significantly between games, and can even switch in the same game (i.e. may be initially bottlenecked by Graphics then bottlenecked by the CPU when a battle ramps up and multiple units are being processed on the CPU. Like in STARCRAFT 2... which also only uses about two CPU cores anyway.)
The LARGER the difference between the CPU and the Graphics card, the more likely you are to have a bottleneck. Since games VARY in the CPU/GPU weighting what we mean by a "balanced" gaming system is that if we took 20 games and tested them 10 would tend to be CPU-bottlenecked and 10 would tend to be GPU-bottlenecked.
But let's be clear, on AVERAGE of the following two setups the FIRST one is by far the best as it's more "balanced" but the second one is far more GPU-bottlenecked.
1) i3-2130 + R9-270X
2) i5-3570 + HD7790
Benchmark (average of many games): http://www.techpowerup.com/reviews/MSI/R9_270X_Gaming/24.html
The HD7790 is about 56% as fast as an after-market cooling R9-270X assuming no major CPU bottlenecks. I can't give you a better comparison of the above two scenarios except to re-state that IMO you are much better off with the R9-270X instead of the i5-3570.
*You can also look up "CPU scaling" benchmarks to see if more than two cores matter but they can be misleading as they usually use a much better graphics card than the HD7790. Again, the WEAKER the graphics card is the LESS likely the CPU is to be a bottleneck.
Other:
I should add that at 1366x768 it's important to use anti-aliasing to minimize the aliasing (jagged edges). This requires a good graphics card to keep frame rates high not a better CPU, and even at 1366x768 you may use more than 1GB of Video RAM which is likely what your HD7790 has.
