I've got an 8800gt system and I'm managing with no problems on a 460W supply, it is pretty barebones though, i dont have interest in fancy soundcards or whatnotBulletinmybrain said:Custom building a desktop is the best way to get the most bang for your buck. Then upgrade to a LCD 20"in Moniter later on. Also remember if you get more then one hard drive and anything more powerful then a 7800 NVIDIA(I think.) then you will need to probably upgrade the powersupply to 500watts since 420 won't cut it.
