Hi D,
Thanks for the welcome. I realise that I need a new
PSU for the graphics card im thinking of purchasing as I'm currently using the
PSU from my old PC. I was able to run Halo on max settings on my old PC without any problems whatsoever (as I am with this PC), and (like you) only able to run Crysis on low settings with low FPS (20 - 40FPS).
The only improvment I can see is:
XP runs faster
Sims 2 runs on higher FPS (camera still jerks)
Mame (arcade emulator) runs more smoother and more stable.
I can run Call of Duty 4 on Medium settings excellently.
Everything else is still the same.
Maybe the graphics card is bottle necking the system after all.
