I'm hoping someone can give me a hand. I bought ROF about two weeks ago and I cannot get the simulation to run past 10-15 FPS at 1680 x 1050. I've been told its my video card. I've done some research and I found the Galaxy 9600GT Low Power/Low Profile that is supposed to run using a 300W power supply. If I bought that card would that improve the FPS? Are there any other cards out there that will boost FPS without having to buy another power supply? Any help would be appreciated. Thanks.

Dell Inspiron 530

Check the recommended RoF spec:

Even though it's a Dell and overclocking is not an option in the BIOS (I think), you can still overclock that CPU. It should have no problem running at 3.0 GHz.

See the following link to a video on Youtube on how to overclock your Q6600 in that Dell

Adding the 9600GT would also give a decent boost over the 4350 but in all honesty if you want a bigger improvement don't waste money on a lower end GPU. Use it to buy a better PSU and and a better GPU or you will just be wasting your money. IMHO of course.

Right.
For running the game at the max. I always check the suppliers recommended games spec's and go one step higher, because they are optimistic. So a HD4850-512mb, will be in my view a HD4870-1Gb.
And read the forum recommendations, because for some games a Nvidia card is a better choice!!!

BTW do always a stress test and a temperature log after overclocking, miss this in the video. If OC will make sense here, you can use programs like CBI or Systool for doing CPU-voltage and RAM tweakings, to get more out of your rig, but you will find then all on Google search.
