PC Upgrade Advise. Any One Help?

Loonylionoh yes it probably would handle a 5450, I assumed you were still talking about the gtx 465.

Not very well. Asus X450 cards are budget video cards. They will meet minimum requirements but that means you'll hjave to run the game at low settings. Higher setting would be laggy.

that PSU has a 60A 12V rail so it would be able to power a GTX 465 if you decided to upgrade to one at a later time
