Oh shoot sorry 420 watt Thermaltake PUREPOWER Model #W0009R 420W+Dual fanHow many watts does your psu have?
Thx for the quick response, the other video card that was in the sys was a 6600gt so the only change was the vid card.....and then all the anomalie probs started....You should have enough power. One of my system has 7800GT with 350watts and runs fine. As for the anomalies on intensive games, get more ram for total of 2Gb for more performace on demanding games.
