What's a better video card. Intel G33/31 Express Chipset Family or 256MB ATI Radeon X1300PRO?

Kids current computer is an Intel Pentium D 2.6 GHz with 1GB RAM with a 256MB ATI Radeon X1300PRO video card. I'm planning to upgrade them to a used Intel Core 2 Quad CPU Q6600 @ 2.4 GHz with 4GB RAM (which I believe is faster), the video card in that machine is Intel G33/31 Express Chipset.

They want to play Minecraft which calls for a minimum:
CPU: Intel Pentium D or AMD Athlong 64 (K8) 2.6 GHz
RAM: 2GB
GPU (Integrated): Intel HD Graphics or AMD (formerly ATI) Radeon HD Graphics with OpenGL 2.1
GPU (Discrete): Nvidia GeForce 9600 GT or AMD Radeon HD 2400 with OpenGL 3.1

So I want to know which video card of the two I have is better so I can put the better one into the upgraded computer. Once I do that, will it be able to play Minecraft?

The G33/31 is about the slowest video chipset that exists…
Based on:
http://www.videocardbenchmark.net/gpu_list.php
it is 905th out of all video cards. It is NOT a "HD" Intel, just low end Intel graphics. Thus it does not meet the requirements.

today's video cards do like 9000.

Anything will bit Intel in the graphics performance

I think they should stop wasting there money and concentrate on high end CPU's

and live APUes to AMD
