According to AMD/ATI's site, that card either has 4 or 8 pixel pipelines... if it has 8, the ATI will absolutely crush that GMA 950. If you've got one of the 4 pixel pipeline cards, it'll obviously be a lot closer... so much so that other integrated options (Intel X3000 series) would probably start to match it in performance. That old card is at least DX9 compliant so that's good.
