I am considering upgrading my video card in the Power Mac listed in my signature. But, I'm becoming skeptical that it may not be worth it for my needs. There's no tight budget that I'm attempting to maintain, but I would like to save some cash if the upgrade isn't necessary. This is the card I was considering, and from reading the performance figures it appears it would be a fantastic value. My typical desktop use is for video playback or encoding (haven't once messed around with video editing, yet - maybe in a few years), Photoshopping, and the regular (iTunes, surfing, Mail, iCal, blah blah blah). I am not a gamer, at all or ever. Is this card a superfluous upgrade or would I see a noticeable boost in performance? My current video playback and encoding seems to be great, but I was curious as to whether I should continue considering this card. Thanks.
