I didn't see the TN panels. No way for graphics work. IPS panels, and do a little research on which type and how much you want to spend, if you're getting 6 of them.
On a personal note, I'll never go back to a TN panel after working on my IPS panels, and I'm using 6-bit e-IPS 2209WA's, not even high end like the one Skuzzy mentioned in his build thread a few months ago.
