But if the r300 driver works without compatibility problems with this feature, I can discard the X300SE 64 bit without Hypermemory and point to a Sapphire X550 256/512HM which seems to have 256 MB on-board and, according to some sites, 128 bit memory bus.

So the entry-level market is a hell of conflicting model numbers and brand names, and most manufacturers and retailers now offer only X300/X550 or X1300 and newer cards. The choice was X550 or Nvidia, and I don't like closed source drivers. Thank you for your time. GhePeU ------------------------------------------------------------------------- Take Surveys.
