Should I upgrade my 3570K to a 3770K?

Should I upgrade my i5-3570K to an i7-3770K?

I have an Asus Maximus V Extreme motherboard, which can overclock CPUs automatically.

It currently overclocks my Intel Core-i5 3570K (stock is 3.40 Ghz) to 4.4 GHz.

I was considering upgrading the CPU but since the motherboard only supports LGA 1155 CPUs, the only real upgrade is a 3770K.

Look at the chart I made below and help me decide if I should upgrade the CPU.

When OC'd, I can imagine it'll hit 10,500.

PassMark rates HT more than games tend to. What do you use your computer for?

General use.

I know it won't do much for my 2560x1440 gaming but it may help my light video editing etc.

Just discovered I can sell my i5-3570K for around £95 and buy the i7-3770K for around £180.

I can't justify £85 for the performance increase.
