Lag again -.-"

[toni007]

Even though i have upgraded my gfx to HD 7750 1GB DDR5.
I am getting lag when ship explodes (tearing apart) also i have noticed this in other games aswell.
like Amnesia,Penumbra...
When there is explosion i get lag.
But over 100 fps in these games when no explosion???
Also i have lag when in external view i use time compression 8x or more ( no lag till 8x )
and i get lag on world map when use time compresion over 2000-4000x ( in silent hunter 4 lag after 5000x )

Than i have told myself than this cannot be gfx problem,only cpu.

I think this shi** cpu is bottelnecking/causing lag in these games (even thought no lag at 99% of time)

so here is my specs:

CPU : Intel 2.2 GhZ dual core e1500
RAM: 2GB DDR2 800MHZ
GFX: HD 7750 1GB DDR5
PSU: CORSAIR VS 550W
HDD: TOSHIBA 500GB

I think cpu causes this lag. I am planning to upgrade it to intel core 2 duo 2.9 GhZ
My motherboard supports only socket 775 processors.

any advices?
