Which gaming monitor should I get?

Lenovo ThinkVision LT2452p (=brightness: Panel: IPS, 7ms response time, static contrast ratio: 1.000:1, dynamic contrast ratio: 10.000.000:1)

Dell Ultrasharp U2312HM (=brightness: Panel: IPS, 8 ms response time, static contrast ratio: 1.000:1, dynamic contrast ratio: 2.000.000:1)

BenQ EW2430 (=brighness: Panel: S-PVA, 6 ms response time, static contrast ratio: 5.000:1, dynamic contrast ratio: 20.000.000:1)

Since I can't see this monitors in real-life action it's really hard to choose. In which order should it be? Best: number 1 Worst: number 3. I'm going to use it for games.

Added (1). I'm not RICH! And that LG monitors are TN panels. TN panels have very bad contrast ratio.

Don't bother with those.
get something better, see the LG 3d monitors here…
