I have:
Athlon XP 3000+
1gb Ram
Geforce MX 440
120gb HDD

And I want an update! lol. The priority obviously is my graphics card as it displays high res textures extremely strangly in the viewport and the most recent games don't play on it. So what's more important when looking for a new card?
Pipes, Ram or the speed???

Any ideas on what I need? Or can people give me their computer specs and an idea of how well it works for them.

Oh yeah, btw. high res videos run slowly is that graphics power, Ram or CPU? This is something i'm keen to sort out as I make short films as a hobby.
