So, I saved up my pennies, headed to my local hardware store, and got the Antec Truepower Trio 650W (as they were out of stock of what i was looking for and i was impatient).
I got it all set up but still am having the same problems as before. I have tons of jaggies and the performance level is not where i'm sure it should be. Although it is much quieter than before.
I am using nHancer, activated the profile, and nothing changed.
