So, I'm thinking of buying a silent low-profile graphics card for my PC. One of the following:

(from cheapest to most expensive)

GIGABYTE GEFORCE GT 210 1GB DDR3 PCI-E VGA/DVI/HDMI LP SILENT

ASUS RADEON HD5450 512MB DDR3 PCI-E VGA/DVI/HDMI SILENT LP

SAPPHIRE RADEON HD5450 512MB DDR3 PCI-E VGA/DVI/HDMI SILENT LP


I'm inclined to buy the second card, but I'm not sure just how much of a nightmare it might be in the latest Ubuntu. If it's too much of a hassle, maybe the first one would be more worthwhile!

Any thoughts?
