current one is an LG 27 inch, mainly used for gaming at 2560 x 1440 res, however i am thinking on upgrading the pc, or building a new one capable of the latest games near 4k, not sure of the price range, possibly round £800 or more if possible, and i would want it bigger than a 27 inch, possilby 34 - 38 ? any gamers have a similar set up, opinions for desktop use ?
