So basically my brothers just bought Minecraft and after installing it they realized they can't run it - their GPU doesn't have a OpenGL support. They might even have some old integrated gpu or something instead of a real gpu.
Current specs of this computer are
CPU: Intel Core 2 6400 running @ 2.13GHz
RAM 2GB
GPU Intel G33/G31 Express chipset (The integrated one then i guess).
So my brothers dicieded to upgrade that PC to run Minecraft and other similar games somewhat smoothly. They are planning to upgrade the GPU but I wonder ifthe CPU would start to bottleneck the system too much? The GPU they are planning to buy would be in 180euros price range. So what would be the best thing to upgrade with this money to be able to run minecraft smoothly on this system.
