A system with a 7850 under full stress comes to around 285watts of power, so, do the calculation a 430w PSU also can run it.

A 7850 consumes 106 watts of power while gaming
Total system power usage is 285watts while gaming
I suggested u a Corsair CX430 V2 whose output is 450watts with 85% efficiency and its cheaper too.

May I suggest that you buy this one --> http://www.corsair.com/en/power-supply-units/vs-series-power-supply-units/vs-seriestm-vs650-650-watt-power-supply.html
Corsair VS650 (650 Watts) ~70 USD
it is a non modular PSU, not 80PLUS certified though, but just like everybody in this forum says, corsair is just a rebrand of Seasonic and thus, having the same performance as those of the Seasonic PSUs...

I would not purchase a CX430. Your total usage power wise may be around that but you are putting a incredible amount of strain on your system by doing so. Do not go cheap on your power supply ever. Start at 7:29 in the video. A TX, HX, or AX Power supply from Corsair would be optimal. Also these are good solutions as well. The lower end series from Corsair are non seasonic the components inside are cheaper.

Its possible for you to experience this. You have below a i3.i5, i7 processor so I can see how it may be possible for it to bottleneck yes. With a mid range card you should be okay but I can't tell you for certain. Either way you are looking to upgrade in the summer you said with Haswell. SO please do yourself a favor and get a 2 gigabyte 7850 so you can enjoy the games that do spill over the 1 gigabyte mark which there are games that do.
 
Well that all truly depends on your case situation if you have a lot of airflow running through the case or not. If you don't it may be better to get a blower design card (reference) as it will help dissipate the heat a bit more. However if your case has a decent amount of air flowing through it then a non reference card will provide superior performance to your card then a reference solution.
