Specs:
-- "Willamette" Pentium 4 @ 1.5 GHz (socket 423) 400MHz FSB - quite a vintage!
-- 3 x 512MB PC133 non-registered non-ECC Kingston SDRAM
-- 160GB IDE HDD
-- Motherboard only supports AGP 4x
Recently, I bought SAPPHIRE HD 3850 512MB GDDR3 AGP (priced at above RM400) to replace Nvidia Geforce FX 5500 256MB AGP.

"I would count on the 512MB to 1.5GB range for lag-free game play."

HD 3850 needs a direct power supply from PSU (I haven't figured out the Watt value of that Acer desktop PC yet). But, it runs well after installing the ATI driver (CCC 8.4) provided together with the card in Windows XP. The card is too long and I had to remove the HDD mounting bay and repositioned all my HDD to other locations inside the desktop casing.
The thing I haven't done is to set the AGP aperture in the BIOS (S81M). Probably due to a bigger video memory (512MB GDDR3) and a limited system memory (1.5GB PC133 SDRAM), I will set a lower AGP aperture size (range available from 4MB to 256MB) but good enough without robbing too much of system memory so that the available system memory can surpass any modern game's system memory requirements. I wish I could upgrade the system memory to 3.0 GB (if and only if I could find very rare 3 x 1GB PC133 SDRAM)
From my experience, the Pentium 4 1.5 GHz maximizes its CPU usage when working with CPU-limited (multi-tasked/multi-threaded) software applications. There are a few jumps on system memory usage but not as critical as the CPU usage.
When using Nvidia GeForce FX 5500 on this system:
NFS: Underground - It ran nicely at higher setting and with a better FPS (good enough for a 3D game with minimal system requirements)
NFS: Undercover - It ran terribly at lower-setting and with a worst FPS. It could only generate broken 3D polygons. Movie cut-scenes played at slow rate
When using SAPPHIRE HD 3850 512MB GDDR3 AGP on this system:
I haven't tried yet since I have removed a lot of 3D games prior to installing this GPU.
Is there a support in the PC game so that it can scale up/down the software-controlled multi-threading support in the game (as it can influence the load on the CPU although correctly programmed threads can complete faster)? This is helpful for single core processors like "Willamette" Pentium. The 100% CPU usage for a multi-threaded game is only good for multi-core processors as it has a lot of cores to spare. But not for single-core processors as they need to handle multiple processes and multiple threads on a single core.
I will give more feedback soon.
