A pretty cheap setup. The benchmark reported around 15FPS with minimum settings, which is ok for a Pentium 4 with an 8500GT. I don't care much about resolution and details, I just wanna play! Maybe a processor upgrade will boost performance.
In this setup, I just upgraded my motherboard from my Inno3D SLN73VM that got its BIOS corrupted. I couldn't flash it. No performance increase on jumping to the Asus with pretty much the same specs! But I did upgrade my graphics from the old 6600LE 128MB. GTAIV also ran on my old setup, but it looked more like a slideshow than a game.
Haha, I'm still not eyeing a new VC yet...mine's under a week old. I'm ok with the laggy performance of the 8500GT. Maybe I'll get a 9600GSO when I hit the bigtime.
