Well, I've been playing Rift for over a year and countless mmo's and been able to play on high/max settings with good fps, literally no problems.
Until I realised what my graphics card actually was.. NVIDIA GeForce GTS 240. I don't even know what kind of crap Dell gave me as I spent £1,500 on the damn pc.
Checked what was happening on GPU-Z because my monitor kept going on sleepmode recently.. It was running 100°C and 100% on the fan.
So, some of my other friends (which are gamers) advised me to get the NVIDIA GeForce GTX 560 Ti. As I'm a semi - hardcore raider (spending over 6 hours a day every other day) And need something that will last and keep cool.
If you need any other information regarding my PC, feel free to ask - thanks.
