3ish years ago I built a system that was awesome. Now it's severely showing its age. The system is built around a Asus p5n32-e sli. There is only one processor upgrade that is in my price range for it but I'm thinking I want to get a faster video card first. My video card is a 8800gts. I know there are been several major upgrades to the vid card market. I know ATI is now producing the best cards out there (if you're rich and/or insane) But I don't know what else has changed. I mean, is having a x16 pcie port enough these days? What about power, I have a (at the time) top of the line 800w psu, is that enough? Also, if it is enough, will I even have the right connectors on the psu to power a new card? So much confusion ... I really need to stay abreast of all the changes from here on out and not just crawl into my hole after I get a system put together.
