i think it's the cpu....but wait for more replies :p

I think that you have a program that is using a large amount of system resources or an overheating issue. Your CPU should be faster and your video card is better. I don't think that you have a bottleneck, I think you have a system problem. Your system is better than your brothers and should be performing better. Run task manager and look for a program that may be running that is a system hog and check your temps.

My temps are good, but i dont think its the system exe's either.. i've since i can remember always shut off much of the auto startup and system start up's..

try formatting and install a fresh copy windows

My question is what particular games are you having an issue with, if you can post back with the game's that you're playing and which ones you feel are giving you low FPS I can absolutely help with troubleshoot this issue but based on what you've posted I do not have enough information to provide a response I feel would be helpful for your current situation.

Im playin all kind of games :p  CS 1.6, CSS, GTA IV (Understand low FPS), Mafia II, Borderlands, Burnout Paradise, GTA Episodes (Understand aswell) but all running better on my bro's computer.. The HDD is 3 days old, and i have the latest drivers aswell. BIOS too.

motherboard drivers ? should be on disc that came with board.. ( will connect to board site for download )... bad memory set up. check bios for that. open device manager and look to see if anything needs updating. Have you checked microsoft for updates ? maybe the system is drawing more than the PS can deliver?
January 18, 2011 2:13:58 AM

Everything is up to date, and the memory is supported. The only thing left is as u said, the system draw more power than PSU can handle :/ 
January 18, 2011 3:09:53 AM

I could care less if the memory is supported. If the timings aren't right or the voltages aren't right your machines performance will suffer. As far as the power supply............ borrow you brothers for 10 minutes.

PSU should be fine,Q9550+ GTX 470 pulls about 300W from the wall under gaming load.

Try backing off the OC on the GPU?

What size monitor and what resolution are you /brotjer running, try droping the monitor res and if that inproves it i cracked it (ha ha).

some of you guys are sick..............


forgot to mention monitor refresh rate. wrong refresh rate will cause problems.
January 19, 2011 8:42:04 AM

My resolution is 1024x768 75hz, my brother is also 1024x768 75hz :/  that wierd..

Stupid questions:

Are you running the same OS (inc 64/32 bit) and anti-virus?
Are the game settings / profiles the same (e.g. VSync, AA)?
As swifty_morgan asked, are your RAM timings / clock correct for the spec?
Are there any other performance oddities that might give a clue (e.g. startup slow)?
Do you have any other cards attached to the motherboard (e.g. soundcard)?
Failing anything else maybe run a stability test to check if the machine is healthy in general
January 19, 2011 11:16:15 AM

you have the SSD set up properly in the BIOS ?
January 19, 2011 6:51:35 PM

yup, in raid 0
January 19, 2011 7:02:04 PM

why raid0....... how's about AHCI ?
January 19, 2011 7:28:45 PM

is it better?
January 19, 2011 7:34:09 PM

That's where it's supposed to be set for SSD's. You should look it up.
January 19, 2011 7:44:07 PM

okay, but it was the same results with my mechanic disk..
January 19, 2011 9:22:32 PM

I got something for you to try. Download ccleaner. It's an app that cleans stuff off of your computer. In the settings there's a box to check to wipe free space... ( under windows tab ) Put a check mark in that little box... ( along with other stuff that's already checked )..... Run the app. It'll take some time because of the "clean free space" but just go with it. It over writes useless stuff with zeros to help clean up SSD's. See what happens afterwords.
January 19, 2011 9:24:01 PM

and you did disable disc defrag right ?.... and indexing ?? You need to read up on care for your drive. They are different than regular HD's.
January 19, 2011 9:28:19 PM

i konw :3
January 19, 2011 9:28:24 PM

January 20, 2011 12:40:44 AM

swap power supplies with him see if it is any difference.
January 20, 2011 3:07:03 AM

By your system specification, i think ur pc requires more power. Your PSU is not enough (especially for ur graphics card).
January 20, 2011 3:07:04 PM

an off the wall suggestion, make sure that the game is in the profiles from nvidia, i.e. add>navigate to game .exe

did this on bf2bc on my gtx470, AA started working properly, when from 30fps to 90+fps. and finally got to full gpu utilisation. The game was installed after the drivers, so it should have been ok, but was not.

How??

control panel > manage 3d settings > program settings > add etc.
January 21, 2011 11:59:20 AM

nvidia control panel, i.e. right click on desktop
