I am currently in the process of choosing a new graphics card to put into my system. I play GW, UT3, and FarCry2. I have tried asking questions on a couple different forums, but have not received any responses whatsoever

So, here's my situation: I have two cards in mind. The first is a PNY GeForce 9800 GT 1G($149). The second is a EVGA GeForce 9800 512MB ($109)
My question is: Should I the extra $40-$50 and buy the 1G card, or buy the 512MB card?
UT3 and FarCry2 both are very demanding games, and I want to know if the extra 512MB of GPU memory will make a decent difference.
Thank You!
