[Build help] I need some advice

Hi

I got a old desktop PC HP a1215 and im thinking of getting a new gpu. My PC has a Intel Celeron D 351 and a 300w psu pci e x16. I was thinking of getting a GeForce GT 520 1GB. Will this work with my PC ? what should i be able to run. Will it bottleneck is that a bad thing i don't mind if the card does not run at full performance just as long as it can run basic games ok

thanks for your time
