Radeon 9600pro on 22" 1680x1050 ???

I intend to buy a 22" wide monitor with a native resolution of 1680x1050. My questions are these:

1. How will my Radeon 9600pro 128MB card perform on such monitor resolution? (I know that games won't be playable except in resolutions I already play them in.) I'm more interested in watching Movies, photographs, surfing the internet etc.

2. Also I have a notebook with Mobility Radeon x1600 256mb. How will it perform on such a monitor?

Or should I just invest in a better graphic card like AGP redeon 2600pro that I can afford without making huge changes to my PC?
I'm not planing to change my whole configuration, because it isn't being used more than lets say 2 days a week.

Edit:
Configration:
Athlon 3200+ Barton
Asrock K7S41GX
Radeon 9600pro 128mb
Segate 160GB

Notebook:
Core Duo T2300
2GB DDR2 667MHz
Mobility x1600 256mb + 256 shared
100GB Hitachi

The 9600 pro will support 1680x1050 resolution via DVI or VGA.Your 9600 will run a 22" LCD just fine for general usage, such as watching movies, doing photo editing, surfing the internet, and so forth. For the most part, all that type of usage is going to be more cpu and memory intensive and the video card will have minimal effect in most cases. For gaming, you will not be able to play any modern games at 1680x1050, but I honestly wouldn't be surprised to see some older games run fine, if they support that resolution.

Your mobility x1600 will be much the same boat as the 9600, it'll be great for daily usage but gaming will suffer in some cases. If your playing more modern games you may struggle to keep 1680x1050 playable, but older games will work fine. It will be more powerful than the 9600, especially given the faster CPU and additional memory in your laptop compared to the desktop.

If you are interested in comparing the stats of the 9600 pro to that of the x1600 pro (desktop) you can refer here. As a note, the mobility x1600 runs at 470mhz core and runs the memory at 470mhz (940mhz effective), so it is only marginally slower than the x1600 pro desktop variant. Architecturally they are identical, just the mobility version runs cooler and with lower voltage.

If you are serious about making your games run better, I would suggest upgrading that 9600 pro, hell even a 9800 pro is gunna be a fair bit faster...though it is the same "dated" technology. Personally I would just wait and see if the games that you play run well enough before I decided to buy a new video card. If the x1600 mobility plays them well on the new monitor, that would be a good jumping off point as to what card to purchase.

hope that helps.

Mr. Stang, thank You for your time and effort.
I only needed a confirmation of my assumption, and Your reply gave
me that. Again, thank You.

Considering the fact that my main occupation is programming, and my spare time activities mostly include watching movies, surfing on the internet, photo-editing, online chat etc... i decided to exchange my 15" no-name monitor for a new 22" wide one.

And for my computer games playing - I'll just continue to play on my 14.1" laptop and it's default resolution, it runs games well enough for a 2-years old model.

Thanks again.

A new Samsung SM 2253BW comes this Friday.
