Can i use this video card on my system?

okay, at the moment i only have 512mb of ram. I'm soon upgrading to 8gb.



but i already have a 1gb video card, and im very impatient. will this card work on my system, being that i only have 512mb. i dont expect to see any performance leaps, i just want to make sure it's not going to fry anything.|||1 gb dedicated video card needs a minimum of 4Gb ram, the card wont work and if it somehow does you'll have series performance issues.
