I am not much of an expert when it comes to find out what graphic cards are best. I've been thinking about buying one of these graphic cards, i can afford them both, and my powersuply fits them both. But which are really the best?
The NVIDIA GeForce GT220
ATI Radeon HD 4650
My best wishes.

Based off of Tom's Graphics Card Hierarchy Chart, the GT220 is the better card. I would recommend looking for specific reviews of each card based on the games you plan to play. One card may perform better in certain games.
I highly recommend purchasing a newer ATI Radeon series (5k+) for DX11 support.
I purchased an ATI Radeon HD 5750 for ~160 USD the day after Christmas, and it supports DX11. Both of those cards will be obsolete in about 6 months.
