but I hate how in older monitors it's harder to see the screen image from an angle.
That is complete bullocks.
Today >95% of LCD's is TN (100% in computer stores not selling Apple), where in 2005 you could find a PVA or IPS screen among the regular crap in computer stores (70-80% TN panels). There are more ancient gems (Acer AL2616, Acer AL2623, Dell 2707, Samsung 275T, HP 2035, HP 2065, Samsung 214T, Samsung 213T) than decent new models!
Oh, and 16:10 is the best trade-off between much vertical space and SF-readiness. If you are in the USA, shut the FK up, grab your wallet and buy this one while it lasts:

Here in Europe ---steaming pile of meadow muffin--- has landed on us already with the sudden disappearance of the Planar-twin: the LG W2600HP

Strange, USAliens cannot get the LG, we cannot buy the Plannar

If you want the
King of all Cosmos, then try to find a second hand (WHO is stupid to sell this?) or stock clearance
Eizo SX2761W. That LCD will be the
Best Gamer LCD Screen EVER Made Indefinitely. It can only be surpassed by OLED, FED, but not by any new LCD model! Serious quality LCD's are a thing from the past. We have to accept that. Early 2010 was a turning point in LCD history with the death of the W2600HP, the Hazro W26i, the Eizo SX2671W and the Dell 2709WP. It can only go down now!
I have little hope that the 10-gazillion-pixel-27inch-iMac-IPS-panel will ever get a 500 euro/700$ cousin in LG/Planar flavour. And it will have too many pixels for your vidcard. Cut your frame rate in half on that panel and forget 1:1 FullHD mapping. There is also little to expect from TV-land. Philips pretends it makes a IPS 24p/50p/60p FullHD IPS 26 inch TV, but that model is nothing but fantasy and website-filling.
