since you are going to be doing some minor gaming, I wouldnt recommend spending much on the video card...if your resolution is 1280x1024, you could get away with an HD4670, which is a decent midrange card that doesnt use much power.
Since you are going to be doing some video editing, you should probably invest in a quad core...along with at least 4gb of quality ram
Ahslan is right, you don't need very powerful of a video card, but the 4670 is only $20-$30 cheaper than the 4850. Should you choose to play some more graphically-intensive games in the future, the 4850 will handle them admirably at 1280x1024.
According to Guru3D's tests, the 4850 will nearly double the 4670's framerates in almost every game at 1280x1024. ~90% increase in performance for a ~30% increase in price sounds like a good deal to me, especially when the price is already so low to begin with.
ok yall r going in the wrong direction for a video editing g card might i mention the 9800gtx+ it was originally designed for it go intel buddy not amd u will be very surprised on how much more stable it is =D
Uhm, nvidia makes the 9800gtx, not intel. As far as chips, I'm a certified computer tech and have my bachelor's, and I've always been buying AMD chips, always had great luck with them myself. But I don't know about the op, but I have to work hard for what money I've got, and can't justify spending more on intel chips.
