I'm about to purchase a new graphics card for the sole purpose of playing movies using a DVI input. My current card only supports VGA input and I'm using a 24" LCD. With that said, does it matter what video card I purchase? I will not be playing games at all so I figure I'll get the cheapest and newest video card I can which as far as I can see it is the MX4000 from nVidia. Will it matter if I buy this video card over, let's say, an nVidia 6200, 6600 or 6600GT? I rather not spend more money than I have to since my motherboard is an AGP version and therefore if I decide later to upgrade my motherboarrd to PCI-E, the video card will no longer be functioning. On a side note, I'm also about to buy a 320gb Seagate HDD. I wanted to get the SATA 2 7200.10 version but apparently my mobo doesn't supprot it. Thus I have decided to buy the PATA 7200.10 for the same price. Is this a mistake? I believe my mobo supports SATA 1.0 but I don't want to go with WD since they have inherently less reliability (3yr vs 5yr warranty). The HDD will only be for storage of movies/video and will not be used for gaming or editing graphics. Will I notice any measurable difference?
