After installing Beryl on my Ubuntu Edgy system, I became addicted to the cool Expose mimicking effects and decided to upgrade my outdated GeForce 4 MX420 card to a 256MB BFG GeForce 6600 OC (The OC means it's overclocked above its normal operating speed). I also upgraded my 512 MB RAM to a set of Corsair Dual Channel 1GB DDR.
I haven't experienced any crashes yet and it has been running for an hour. I noticed that my installation is missing the "Show Desktop" effect, which I really miss.
