I dont know a thing about it... used for transcoding videos... No gaming or overclocking... I'm basically looking at building a config that is future proof for atleast a year.
Transcoding video is CPU/HD/System Memory intensive, not video card intensive. So if you're definately NOT gaming... and ALL you're doing is displaying a screen... then you could have "future proofed" yourself YEARS ago with any video card. The newer, snazzier, fancier, more expensive video cards of today are good for only two things... video games and CAD. If you're not doing either, there is NO NEED for an expensive video card... heck, on the MB video is just fine for what you describe.
Of course you have to be TOTALLY HONEST with what you say your needs are... throw ONE game in a year's worth of computer use, and you may wish for a faster card. If you are 100% honest for your needs, and will ONLY use it for web surfing, book-keeping and transcoding video, then there is no need to spend more then the minumum necessary to see an image on your screen.
GeForce 6's are great if you're going to be doing gaming or CAD work, but if it's general office applications and video transcoding, you can get by with a cheaper card (and still play the occasional Windows default "Solitare" card game).
