If I were you I probably would at least try. But I would not try without a cooling tower or water block. Cooling towers are really cheap; some go for around $20.

Of course that is assuming your processor is not locked. It is next gen so you probably can. I would expect to see a noticeable improvement because you have a really good GPU.

Any idea how high you might want to go?

I would think around 4.2Ghz is nice to get but i have a question what do you mean by Cooling towers?

I think he means air coolers. A.k.a. the Cooler Master Evo 212 or similar.

If the i5 or i7 processor has a "K" at the end it's the overclockable version.

To OP: I would definitely try to overclock. Obviously you will need a third party cooler installed on your motherboard.

A big air cooler that kind of towers over your motherboard like this:

Personally I wouldn't refer to those as cooling towers. They are fan coolers or air coolers.

The real cooling towers are passive coolers like this;

those are all tower coolers
that one is fanless

best of the tower air coolers are nh-d14 or silver arrow

4.2GHz is a bit conservative for a 2600K, with a decent CPU cooler that system should hit 4.5GHz easily, with good water cooling (not an all-in-one) you could hit 5GHz.
