im wondering about any tricks/tips for getting better framerates on large 720p+ movie files on the pc.

my current rig is fairly competent. i have an x2 3800+ 2g RAM and an ATI x800 256mb video card.

if an upgrade is in order, then where does the bottle neck lie primarily?

are there any non-hardware tweaks that can benefit me here?

what do you guys think?
any advice would be appreciated!!

What types of file, from which sources?

Slow rates on a downloaded quicktime HD movie would be because of a slow processor. If youre editing hd raw video then the bottleneck is guarenteed to be your harddrive. And just for a laugh if youre playing back 1080i wmv files then it will be because your gfx card doesnt support onboard decoding.

If you're looking to speed up HD DVD and BlueRay resolution movies/video then a Geforce 8600 or 8500 is likely going to be very useful, they off load all of this process to the GPU, leaving the CPU to do other work.. The Higher end Geforce 8 series cards do not support this.

not for editing or anything that demanding, simply playback at this point.

for example HD trailers in 720P play fine, but 1080P is very choppy..

some large 720P files (2g +) with very high data rates are also very choppy.

that's interesting about the Geforce 8500/8600.. ill look into that a bit.

if its just playback, the problem lies in the processor.

Hence the recommendation for the Geforce 8500 or 8600 series cards. They off load 100% of the video decoding to the GPU.

The issue here is finding playback software that supports it :) Check out Anandtech, they have a few articles on the high def performance of these cards.
