Ok so i was narrowing it down between a GeForce 6600 GT or the ATI x850 XT PE. I know the latter outperforms but i'm not that hardcore and im sure both would fit my needs. I am more worried about which is more stable, which is louder (or quieter) and which takes up a lot of hte computers power supply. if anyone can shed some light, i'd appreciate it. thanks ahead of time
