Excellent choice! Yes!

However, why overclock? Graphics cards are usually well optimized.

My answer is very clear, and I have stated the source of my information.

Never take chances with an under-powered, or a low quality PSU.

Whilst it might "work", you will definitely not get full usage out of the R9 380 or the GTX 960 for that matter. As said above, a minimum of 500W is required. Sure, it might run the card, but performance in games will be pretty bad as not enough power will be supplied to the card, and therefore the GPU load won't go above a certain amount (50% in most cases) If you're going to spend the money to gt a nice GPU, just throw a little extra in and upgrade to a high quality power supply. Afterall, what's the point in buying a nice new card if there's a chance the power supply could destroy it?
Hope all goes well with your decision. :)

well lets say if i pushed the clock and memory at it's limit, with no voltage increase , wouldn't that give me a noticeable performance?

I do not recommend overclocking graphics cards because they run hot as is. Overclocking will increase the heat generated and thus create other problems including reduced life.

i would agree with you on that, i'm ok with 30 fps with well graphic settings , maybe in the future i will consider that option.
but i if was going to buy a power supply it's better for me to grab a decent one, so i won't have to change it again for any different reasons.

What 450w PSU is it? I'm running mine on a Corsair CX430 which is supposed to be really bad and yet I've had no issues with it.

You are lucky, MM! I would be a little nervous with a CX.
