The one who grabs the most market share is not the one makes best video card. that is interesting.Intel held its first place position claiming 47.3% against Nvidia’s 31.4%,while ATI,moved to 18.1%, which is the lowest market of ATI/AMD in the recent years. that is interesting too. AMD/ATI 4800 series are good, but it is the "lowest market of AMD/ATI in the recent years".  i think Intel's X3100 and GMA 950 should contribute a lot to the result. lol

the cheaper, the better, more $$$  more market share

The problem with this information is that it represents TOTAL GPU SALES.

That counts IGP (integrated graphics adapter) chips on motherboards, where Intel has its main lead (Go go GMA 950).

But only corporate / home casual customers use IGP's , and those Gamer/Entusiasts who haev IGP's on their motherboards NEVER USE THEM, cuz as any gamer knows, IGP's are the weak sauce.

The sales stats you list are not relevant to a hardcore/gamer/enthusiast market.
