I wish there was a place to play around with high refresh monitors. Every Fry's I've ever been to has 144hz monitors on display but there always hooked up to PCs without any games. See the mouse move around the desktop smoothly is neat, but you'd think they'd have it running a game to show it off.
Same at Best Buy, they always have gaming PCs on display that don't have any games installed, so you can mess around the desktop with a machine they're claiming is a beast gaming rig. I wonder how much more popular PC gaming would be if you could easily visit a retail store and see games like Star Citizen running on high settings, or console ports running at high FPS at 1440p+, or a shooter running at 144hz.
I've really only ever gamed on consoles (I played the Sims and Civ on my parent's old desktop but that's the extent of my PC gaming) but I strongly prefer playing games at 60fps. I assume I'd love gaming on a 1440p, 144hz screen (ultra-wide monitors seem very cool as well) but it's worrying to spend $1,000+ on a PC before I know whether or not I think it's worth it.
