Hi, i've never really been a big pc person and have always gotten cheap not very good pc's in the past so i'm a bit new to it all. On the pc im looking to get from 3xs it says i'll need to upgrade the power unit if using an NVIDIA 465+, the one i was looking to get is a 768Mb EVGA GTX 460. I know its not 465 or over but i havnt seen one that says 465 on it so was wondering if i did need the power upgrade? Thanks
