Bad fps on a somewhat decent comp

My fps in counterstrike 1.6 keeps dropping, can someone tell me how to fix this?
My computer specs:
evga 8600 GT with the lastest drivers with lowest settings (0AA,0AF,high performance) - even tried overclocking it (it's @ 53C while playing cs)
pentiumD intel dualcore 2.8ghz - even tried overclocking it (60C while playing cs)
1gb of ram

when im looking at the sky or something i get 99 fps
when there are more than 2 ppl on my screen my fps drops to 80,
when there are smokes, flashes going off, or nades going off i get around 50

any tips on fixing this mess?
keep in mind cs 1.6 is a 9 year old game...

no, it sounds like its having trouble rendering polygons? sounds like a cpu problem, intel pentium d isnt great, and cant keep up with the 8600gt. So the video card sets up the frames sends it to the cpu and it gets jammed. Not exact, but along those lines.

my mobo wont allow overclocking thru bios

2.8Gz cant handle CS? I cant believe that really.

Can you post up some specs about that PSU, that looks more of an issue.

300 watt psu

Looks interesting...was tryna find some specs...

"There is a very well known problem with Bestec PSU's as used in eMachines and others. The power supply fails, putting out too much voltage, and
eventually killing the machine. Sometimes just the motherboard, other times
pretty much every component in the machine gets zapped. I looked at one
recently where even the hard disk and both optical drives were fried!

Unless you have a spare machine in which to test each individual part, I'm
afraid your PC is probably best considered as a lost cause."

I can only assume that the PSU hasnt got the juice to power that 8600, coz i cant find the specs. But the fact that its a split 12v rail says it all i think. 8600GT looks for 350w as a guideline, 18A of 12v juice.

Thing is...what with this being a Gateway im not sure how easy it will be to swap out that piece of crap.

If you want to go cheaper theres the Antec Earthwatts for a special offer of $35 at the mo which is amazing. Thing is its modular so you need to make sure you connect it properly. 2 rails of 17A juicyness, 1A shouldnt make a difference when you got 2 rails.

erk!! 8600 maxed out on wow
I would imagine that would be down to the lack of quality testing that just adds £££ to the price of these budget PSU's.

I did a bit of further reading, josh dont go buying anything until you have measured the available space and confirmed that any PSU recommendations can fit in there.
If you dont like your money then you can always ring Gateway and ask for a better PSU.
Having said that, i know its a 9 yr old game or w/e but is dropping to 50fps really that much of a problem?

especially competitive cs players.

okay i just bought a 500watt pc power and cooling psu which i heard are one of the most reliable and best psus

still do not get 100fps on cs on my 8600gt... still get fps drops

why are you setting your graphics settings through the nvidia control panel? In CS set the resolution to 1024x768, use openGL rendering, 16 bit color and in the multiplayer advanced tab set the smoke grenade setting to fastest. There is also a console command to set the FPS to 60 but I forgot it.

^^ Translation: Turn on V-sync

All that does is set the MAXIMUM FPS, not what the FPS is set to.

did you even read this?

My old comp had the same setup, only with a Pentium D 3.0 GHz.

Be happy if you can get 60+ steady. Your comp simply doesn't have the power to chug away at games, even at 1024x768.
