AGP8 card advice needed, not for gaming

Hi,

I need a new budget AGP8 graphic card, as I have an unreliable
Matrox 450 in PCI slot at the moment.

Have TFT 17" capable of 1280x1024 at 75Hz with DVI but would
like to budget for 1600*1200 as that would be the next step up.
Another future feature would be TV and HDTV outputs but not as
a priority. I don’t need dual monitors that badly any more.

I usually do Photoshop editing and DVD editing and DVD playing.
I don’t do games apart from some basic ones. I value
reliability more than performance. Last year card will do if
reckoned trouble-free. The budget is up to £100 ($150).

Why ask and not Google? I did Google but all reviews and usenet
articles I have seen so far were written from gamers point of
view.

The system is P4 2.5G, Asus P4P800-E mobo, 1 Gb memory. Nothing
is overclocked but it could be if needed.

I use Zalman’s Reserator 1, silent water cooling system for CPU
cooling (excellent!). They have optional cooler bit for graphic
card processors, it would be bonus if it can be used with the
new video card.

I would value your opinions and experiences.

Thanks

PS I see often similar card with 64, 128 or 256 MB, would more
memory make any difference for me?
