teh ramdac in the integrated 650 is perfectly fine for 1280x1024...it should be for the ECS 315 board as well, unless they implemented some cheap ass filters (which they mostl likely did)
besides that, the 3d isn't supposed to be stellar, but it's got to be one of the best in the integrated market...that's quite good coming from SIS.
also, i'm not planning on upgrading to a faster video board...this one suffices (hence the reason i've had it for 2years now)...also, the case i plan on picking up won't accomodate anything larger than half-height cards...there's not a lot of fast half-height cards out there...nothing much better than the SIS 315.
i'm trying to use as many integrated components as i can, while maintaining adequate 3d performance (i really only play half-life mods) and keeping the cost at a reasonable level....SIS seems to fulfill those needs, by the looks of it.
also, i could always slap in a separate AGP board if i wanted to in the future...granted the SIS 650 and 645 perform equivalently, the system performance will still be quite good.
