asus 8600gt/256mb, $80: http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=10006880&prodlist=celebros
I have a rather elderly Pentium 4 3ghz system . . .running on a megabyte Socket 775 LGA CA81915PM motherboard with I gig of DDR SDRAM memory.
I know it's a bit ancient but the main problem is the graphics card which is a lousy Geforce 6200 LE.
Which nvidia card would be the best upgrade, power-wise and budget-wise, without having to change the mobo or power supply. I don't want to play Crysis at high res . . .just something like Quake 4 or Doom 3 at a decent resolution.
I have a PCI Express slot.
