yes 7-30fps, at 1280x1024, Normal to hight settings, NO AA, AF Full, texture resolution at " extra settings. Shadows is always off, like shadow map resolution, all of that is a waste of time. Keep in mind, i had the game running off my external HD with 1.1 speed. Only because i only have 10GB on my internal, its the same Internal HD from 2000 lol, never really bother to change it hahah. But i have 5GB left now, so i will run COD4 again off my internal and see how it runs , because its faster then my external HD.
Nevertheless, i have Ati tray tools install, so i can use OSD and show you more accurate stats, even tho i was just sharing my benchmarks, don't really have to prove to you, but at those settings in COD4, the game runs just fine. Now recording video is a problem off my external, so i will see can i record from my internal.
I can't even run the game at 800x600 or 1024x768, i lose performance rather then gaining it. But at 1280x1024 everything is smooth. When i start the demo, and you are at the front of the action, it stays between 7-10, but after that part, i get inside the building, i get 15-22, at times i do get 30 if i look at the ground, 27 once i am outside with that rocket launcher thing, taking out the tanks. But once that whole area is cleared out, i get 20 to 30 just walking around.
I think it did help by me fixing those IRQ issues, not that my card is not shared with my sound and all that other stuff.

I will have benchmarks using at tray tools tomorrow.
Yes but what is the model of the tower? Like the model number on the front of the tower.

From 600Mhz to 1Ghz is definitely worth looking at considering a 1Ghz PIII/100Mhz FSB at my preferred source for older processors is only $9. And replacing a CPU is not tough at all, the hardest part is getting the heatsink off and back on which isn't a big deal when you take a good look at how its done.
But if i can't find this item at newegg or in stores around my way, then i am not bother by it. I have a ebay account, however i have no plans to use it right now, for security reasons( don't ask )
The performance wasn't bad processor-wise; apparently a 1.4ghz P3 outperforms the P4 up to 1.7-1.8Ghz. When I had an FX5950 Ultra in it, it ran Battlefield 2 on lowest settings.
I thought' P4 are more powerful then P3's?
