I would imagine for an mmorpg ultrawides are great, so here's an affordable uwqhd monitor.

Otherwise i would suggest 27" rather than 24" 1080p or 1440p is up to your specs/budget in that case, but 1440p does look nicer, and in games like FFXIV it lessens the awful AA on trees/grass especially in distance.
