... It seems these intel gps have progressed a lot lately and that's great ...
i know that they got more power these days, hd4600 and higher models. BUT that are still integrated graphic chips, not a full graphic card. these chips still do not offer full graphic support (for example bump mapping, high res agp textures) and they are very weak compared to real graphic cards of the same generation. so there is no way to prefer intel as graphic brand, its just an emergency solution, in case you can't play on an device with a real graphic card.
of course there are exceptions, like darkstone. it runs great on intel but you can't run it on geforce 400 or higher models without horrible glitches.
I know the people at Intel are working their asses off, but wouldn't it be great if we had integrated graphics comparable to off board amd/nvidia ones, even in terms of "heavy" gaming? I'd love to see that. But the vast majority of games I play are not that demanding, so a brand new Intel gpu must handle 'em all pretty nicely and I'm ok with it... but there will come a time when a real gpu will be needed. so... crap.
Damn you gpu manufacturers, why can't ya make my dreams come true?! :P
