Guild Wars 2 system requirements; some difficulties and questions

Hey there. In preparation for Guild Wars 2 I've been trying to determine my ability, or inability, to run the game at low to mid settings on a relatively modern laptop. The problem being, I know very little in regard to computer hardware and comparing between different kinds of video cards and the like, so I was shown http://www.systemrequirementslab.com. My system has the following: Windows 7, 64 bit, AMD Turion (tm) II P520 Dual-Core Processor 2.30 GHz, AMD M880G with ATI Mobility Radeon HD 4250 video card, 4.00 GB Ram

The problem being, that website is telling me everything checks out but my video card. However, it's also showing me this: Pixel Shader version 3.0 / 4.1 Vertex Shader version 3.0 / 4.1 Dedicated Video RAM 256 MB / 384 MB

The numbers on the left are what's required, and the numbers on the right are what it says I have, so there should be no problem. I'm questioning the reliability of this website, so, would anyone out there with a greater understanding of this stuff be able to tell if I'll be able to run the game on at least minimal settings? I would greatly appreciate any feedback or suggestions.
