I just bought a BFG 8800gt OC 512mb and my fps is only around 100. The same case when I have my 8800gts 312mb and 7900gs. I am wondering if its my power supply not giving enough power.

My PSU: Antec Neopower 480w
CPU: e6420 (stock clock)
RAM: Adata 4gb ram (stock)
GFX: BFG 8800gt 512mb.
Mobo: Gigabyte P965 ds3

I used the newegg calculator and it said I needed 496w. Dont know if this is right. If my psu is the case, please recommend me a power supply.
 
Well Im a little confused. You ONLY get 100 fps.

You only get 100 fps in what?
Using the same case or the same powersupply?

Do you have any instability?
 
Yeah your post doesn't make any sense.

That being said, your power supply "not giving enough power" usually results in it dying or refusing to boot, or at the very least, the system becoming unstable. It wouldn't limit your framerate.
 
Power supplies do not impact FPS directly. The only way a PSU can have a meaningful impact on your gaming experience is if it is a piece of shit that causes your system to become unstable and therefore crash or lock up while you are playing games. Power fluctuations don't cause the hardware to run slower. It causes hardware to lock up or fail in some way. In contrast a good power supply is something you won't even notice. If the rest of your hardware is good, you shouldn't experience any problems and that provides a better and more consistent experience.

Forget most online power supply calculators. Your system won't pull 260watts under full load. Unless there is something wrong with your power supply you don't need to replace it.

Im mean shouldnt a 8800gt do at least 150 fps in CSS?

I have no idea. I don't play CS:S. If others are getting 150FPS in that game with similar configurations and you aren't I'd look at your settings. There is more than likely some other reason besides your PSU that is causing you to lose frames.

Power supplies do not effect frame rates.

You mean more watts on a PSU doesn't increase framerates??!!

I was deceived!! ;-)
 
Okay then. Who can tell me whats my problem is? Most ppl with a 8800gt do around 150+ fps.
 
Well, are these other people using the same resolution and the same settings as you? Although I'm not sure what difference it makes if the frame rate is higher than the display refresh rate.
 
Also
100+ FPS is still great for a video game. No lag there.

Also you probably should read Kyle's Benchmarking the Benchmarks. You're running a CS:S timedemo and its telling you some value of a FPS you should be getting.

If you want us to diagnose your problem Here is what you do:

1)Reformat
2)install motherboard drivers
3)windows updates
4)video drivers(newest)
5)all other drivers
6)programs you use
7)disk cleanup and disk defragmenter
8)Run 1280x1024 and lowest visual settings on CS:S
9)run candid timedemo
10)rinse and repeat until feel you have the performance you "should be getting"

100 fps is fine.

Be careful, pumping all that power to the video cards will require alot of cooling.

As someone else already said, it doesn't work that way. I was mainly kidding about PSUs providing frame rate increases, which is something they don't do.

You get tearing when the frame rate exceeds the refresh rate of the monitor.

Dan you might want to run some benchmarks on your sarcasm detector, I fear it has broken.
 
I plugged my PC into my clothes dryer outlet thinking it would increase my Crysis frame rate. The cat (who often lays on the PC) wound up catching fire and thus my house has burned to the ground. I'm posting from my neighbors open wi-fi. ;)

You do, but I was referring to it making little difference whether it's 100fps or 150fps as the monitor can't display 150fps. As you say, it might even be worse?

The tearing gets worse the higher the FPS is over the refresh/draw rate of the monitor.

CSS is fairly CPU dependant, that is, it does not push the graphics card very hard. I would bet the reason your seeing the same FPS as the other cards is that your actually CPU bound in Source, although i think your CPU is plenty powerful enough. I would format and reinstall before making any further assumptions. I got around 230fps with an e6700 and 8800 GT, all settings all the way up except AA on 4x, for reference.
