i'm planning to sell my 1 year old i7 3770 and upgrade to i7 4790k together with a new mobo and rams. will the difference still be worth it cpu wise? i'm also planning to OC, but it's my first time.
It's not worth upgrading that processor. It would be best to wait for Skylake and DDR4 before you spend a huge amount on a new processor, RAM and motherboard.
You could see a difference if you are doing certain things, but if you're just gaming, you won't see much of a difference.
