Which setup would you buy given the following circumstances:
I can get a pair of refurbished u2410s with an add on 2 year warranty for roughly $650. I found a source for the dell u2711 for 750/monitor. so the dual 27" setup would be 1500$. Big price difference bewteen the two setups, but I hear that the 27" inch monitor is superior due to higher resolution. I have a 27 inch iMac right now, and I am used to the screen after 2 years of use, although I do find myself squinting to read text sometimes.
These monitors will be powered by an NVIDIA quadro 2000d video card.
If it fits the budget then get the 27" monitors. You may also want to take a look at the HP ZR2740w on newegg for $679.99 per monitor. I would read these two reviews and decide from there depending on the features you need.
