Is an ATI Radeon HD 4350 better than an Nvidia Geforce GT220? Need Answers Fast!!!?

Hi, I'm customising a PC online and my model can either have an ATI Radeon HD 4350 or an Nvidia Geforce GT220. I am gaming on a budget. So I aim to play most games on high detail or medium. Just wondering which is better and how much better it is.|||GT220 is better than HD 4350 as its 40nm compared to 55nm resulting in better clocks and also cooler running.|||Okay, then you should get an ATI 4850 it's like $150 and just about the best value I have ever seen in.|||NVidia best for all time
