I don’t do games. it’s just to make sites and some rendrings of videos. photoshop, ilustrator, flash dreamweaver… and some premiere.

I don’t know if i should buy 800mhz memories because i don’t wanted to spend that extra money (about 80€ more)
Should i go for windows vista or stick on win xp? the price is the same…
