I have a sistem I only use for photoshop, with 3 monitors. 2 connected on my main video (gtx 470) and one to another card. my question is how powerfull this second card must be and how is it used ? I now have borrowed a gts 250 (512mb/256bit) but in GPU-Z it only shows 90mb used on it even if I open 5-6 tabs with flickr groups on that monitor, but the first video shows increased load to 400-500mb. So even if the broser is displayed on the monitor connected to the gts 250, it loads on the memory of the first gtx 470 card. So, how is a second card actually used ? Am i correct i could get away with buying this gts 250 or I need something more powerfull.
