Thanks for the link, i must say, the LMCE wiki is pretty big, i've been reading it for the past few days and still hadn't seen that particular page...
About the nvidia chipsets, i noticed the 6200 is listed as a working card, but can't i get a better one? Seeing as i'm spending the money, i'd like to actually make an improvement because the 6200, while cheap, is in the same range as the X300...
Would something along the line of a G8400GS or 8500GT work well? Or will this make things difficult with LMCE setup?
I would suggest not going for an apparently more powerful/higher spec card like the G8400GS or 8500GT. Those cards will not perform any better (in terms of LinuxMCE) than a 6100/6200 card and can cause problems with drivers (although that is less the case now). All of our products are based on onboard C51 (which is a 6150 class chip), on board 7050 or 6200 based PCIe cards. The key thing is to find a card that has the outputs you need - eg HDMI/DVI/Component etc
