Hi. My computer is about 3 years old. I haven't made any significant upgrades since. It has 1.5gb of ram and an AMD Athlon 64 1.8ghz. I also have an nvidia ge force fx5200 (128mb ram I think there). Anyways, I use this mostly for video editing and it suits my needs. I have noticed some video is beginning to get kind of choppy. Not so much video on this machine, but online video in full screen. For example, I can watch video on nbc.com or cbs.com embedded in the web page and it plays out fine. When I make it full screen, it becomes choppy. I don't think it's an internet issue because I think it's the same stream, just stretched. My question is, does this sound like a video card problem? If so, what kind of card do I REALLY need to make this all work well again? I dont have PCI express. Again, I usually just use this machine for video editing and watching some of those video sites online. I don't ever game. Thanks for any help you can give me!!
