Currently, I'm using an old ViewSonic VE710b analog monitor. It's connected to my brand new Nvidia GeForce 550 Ti. While gaming, despite being told I have a high fps, it seems unreasonably low. For instance, in Minecraft, I typically play on far render distance and with a 128x texturepack. This used to be fine for me, nothing appeared to be wrong, but in the last week or so, I can't do that anymore. When I do, it says I have around 50 fps, but it appears like I have ten. Before I buy a new monitor, I want to make sure nothing is wrong with the computer I built a month ago. Any ideas? Thanks
