Dell GX745 MT Upgrades - Graphic Card and Power Supply

Hello..
So I'm planning to buy an used Dell Optiplex GX745/755 Mini Tower.

Specs:
Intel Core2Duo Processor
3GB Ram
256MB ATI Radeon 2400
305w PSU

Overall Specs: http://www.dell.com/downloads/global/products/optix/en/opti_755_techspecs.pdf

I want to upgrade the power supply as well as the graphic card. I'm going to be video editing (mostly 720p or less), Photoshopping, doing animations with Adobe Flash, Programming, and Web Designing.

So here are the upgrades I chose:
Cooler Master EXTREME 500w PSU

Evga GeForce GT 430 1024 MB DDR3 PCI Express 2.0

So what do you guys think?
I wont be buying a new computer for a while and this should be a good upgrade right? and of course, I'll update the RAM soon.

Thanks.
Peace.
