I run an AMD X2 6000+ but I only do 2D print graphics, so 256MB x1200 is more than adequate for me. XP64 on it, runs great.
A friend just put together a quad-core Intel with twin 640MB 8800 videos cards, dropped over $1200 on the CPU. Then he put 32bit XP on it for game compatibility.
I spent around $300 on my upgrade, he spent over $4000 at ncix
My parts are on the shelf. His took 5 weeks to trickle in…
I also have a 4-CPU Xeon 700 server sitting in a store-room that cost the original owner over $10K. It’s a fucking slug compared to $200 AMD Sempron 3000 server.
