do I need to upgrade my GPU for good CCTV playback?

Hi, need a little advice.

I have to playback/go through 30,000+ JPEGS daily which have been recorded as part of my CCTV system. This takes forever. I have a Core 2 6600 (stock speed), 1950Pro (stock speed) and watching images saved at 1280*960 on a screen set at 1600*1200. The software I use seems to be playing it back at roughly 5fps max. It speeds up for lower res JPEGs so I imagine a better GPU would make the playback quicker.

As everybody seems to be saying the 8800GTS 320 is the card to have, do you think it would substantially improve the JPEG playback?

I am also an occasional gamer, using another monitor at 1400*900 (2 monitor setup, 1 for CCTV playback, 1 for general PC duties) for Oblivion, Half Life 2 etc., and I know it would improve those games.

Any advice would be greatly appreciated.

Cheers,
Welshie

It's not the software, I can explain.

I have the Folding@home software running, if I pause it the playback speeds up, also if I use any other software it slows down, so I'd imagine the playback speed is largely hardware related. I'm running a 32bit version of XP, so the 4GB of RAM is overkill (I'm aware that 32bit OSes can't utilise the full 4GB of RAM), I don't want to change the CPU as it's the most expensive option, and I should be able to overclock in the future if need be. I have the latest ATI driver for my 1950PRO.

I should have explained that in my first post to be fair.

Maybe I am wrong, I'm no expert. Let me put it another way. Viewing JPEGs is a 2D process, would the 8800GTS 320 be much better than the 1950PRO?

It's a basic CCTV application called Crime Catcher. I wouldn't recommend it, technical help is almost non-existant.

I'm not saying F@H is the problem, all I'm saying is that when I view the JPEGs with nothing else running, they seem to run at roughly 5 fps, but when I start up another application, it can slow down to 2-3 fps. When I'm not viewing these pictures, I can multi-task like there's no tomorrow. I have processor scheduling and memory usage set for programs (is this the best?), my 'Visual Effects' are set for best performance. I have a 3DMark06 score of 5560, which even though it isn't breathtaking, I believe it isn't bad for stock speeds for my hardware.

Problem is, my elderly neighbour has been the victim of vandalism and threatening behaviour by local druggies, and we want to visually identify them, and it takes me forever and a day to trawl through all the images, any way to speed up the process would be a godsend.

They are stored on my 2nd HDD, like to keep them seperate from my main HDD otherwise it'll be bogged down. Each day takes about 10-15GB depending on activty.
I don't want to convert them to an AVI or similar because I want to be able to isolate pictures with people in them, and then delete the ones without. Makes the housekeeping easier.

try making proxies - compressed copies of the images, but that would take some time though. Is that 2nd hd new or 'vintage'? have you checked for errors/defragmented?
