Graphics upgrade help

[pleb]

Alright so this is my pc: ( http://h10025.www1.hp.com/ewfrf/wc/document?docname=c04079597&cc=us&dlc=en&lc=en#N54 ) Im hoping to upgrade my graphics card from the AMD Radeon8670D to a Gtx 750 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814487025). But the issue is I dont think it will have enough power (as It has 300w supply) or if it will work because of the compatibility with PCI or something ( having a msi 2ae0 motherboard). Will it work?

I suggest you get a new power supply, too.

So with the new graphics card it wont be able to run with my 300 watt supply? also doesnt superclocked/overclocked products break quicker or of some sorts? Also my motherboard has a slot of PCI 2.0 and these graphics card say they have 3.0, would they not work?

Your graphics card might run with the current 300 watts power supply, but I, and everyone else here recommend upgrading it, because the one that comes with the computer is of low-quality, and with a good-quality power supply you can expect more system stability, reliability, and forget about the potential damaging to other components.

With good cooling, an overclocked graphics card can live as long as any other one with stock clocks. The SC edition is factory-overclocked, so you shouldn't worry about the life expectancy. Also, for the same price as the normal one, why not get it?

PCI-E slots are backwards compatible. A PCI-E 3.0 GPU can fit and work fine in a PCI-E 1 slot.
