Graphics card for a dual dvi 19" TFT setup

I am currently looking at 2 cards for my main rig - a S939 opty 144 with 1 gig of ram, A8N-E mobo, etc. I have my eye on two - can anyone advise me which to go for (no gaming/encoding needs - just boring stuff): http://www.scan.co.uk/Products/Compa...432&CPID=15084?

The 6800 is by far the best choice there. That 512 ram is completely pointless on a 6600 card.
