i5-4690K Overclocking and onboard GPU

[felt]

Hey guys, I'm building a new system and am still unsure what dedicated GPU I am going to buy, in the mean time I would like to use the onboard GPU on the i5-4690K and overclock the CPU to around 4Ghz on air cooler while using the onboard GPU until I buy a dedicated graphics card.

Will this cause any problems?

Can I overclock the CPU and use the onboard GPU without any issues?

Once I decide on a dedicated graphics card, can I just install the drivers for the new GPU without reinstalling windows?

Thanks!

1. No
2. Should be fine, but the only way to know for sure is to try.
3. Yes, no problem at all. Install the card, switch the monitor and install the drivers.
