The key part of Buck's statement is "feel like an IGP." AMD's low-end discrete cards are more or less the same hardware they build in to their chipsets and nvidia's aren't any better.
On the other hand, I'm not sure that I care. A Radeon 4350 or Geforce 9400 is respectable enough for business needs and can manage video decoding and low-end gaming just fine.
Based on BingBangBop's link, this passively cooled Radeon HD 5450 Sapphire seems reasonable for $26 after rebate. A Radeon 5450 must be better than an IGP, no?
