I have to say I'm impressed this is the first upgrade I've made and actually have seen a great noticeable difference. I went from an 2700 xp oc to 2.41 with the asus a78nx del. to a64 3200 and the gigabyte k8n pro. At default settings I get 21000 from 18200 in 3dmark 2001 se. But benchmarks are not the real story playing the games is. I'm a huge sof 2 player and this sounds weird but my rig is almost too fast(HEHE). My upgrade costs 450.00 not bad. Im an upgrade pig I change hardware every 6 months religously and this is the most satisfying to date!
