I've currently got a NVIDIA G Force FX 5200, 128 MB card. Should I be looking for a larger card to run W 7. Having read a lot on this forum, it appears that I would need something bigger to run Aero. I've 2.27GH CPU, 2 GB RAM, and 500GB HDD. I don't do games, and am well into photography and writing. Your advice will not fall on deaf ears and will be greatly appreciated.
