I have an opportunity to get a relatively cheap HD 3650 (AGP, 512MB DDR2 - original buyer doesn't have AGP) for my older socket 478 system (which I intend to keep by the way
) with a P4 running at 3.0 GHz with 2 GBs RAM. I am aware that bottlenecking will be an issue, but I wonder if I would actually see any improvement over the 7600 GS (AGP, 256MB DDR2; passive cooling) I am currently using. I'll be doing some video playback (HD content likely to pop up from time to time) and mild gaming (that is, CoD4 and stuff on a 19-inch screen). I thought my games would probably not run faster, but look better because I could finally crank up visual settings such as shadows which is currently impossible 
OS is XP, Vista and Ubuntu. Oh, and I'm using two monitors of course... should I go for it and spend a few bucks on this?
