Turns out i'm an idiot. That's just the adapter cable they give you if you don't have a 6 pin from your PSU which I do... got that straightened out.
Would my GPU be bottlenecking due to a lower CPU now? When running LoTRO i'm lagging more than I did with my old Gefore 7600 that ran hot as a mofo...It's an AMD Athlon 3500. I plan on getting the II X3 450 as it's $70 w/the promo code.
Also, i've been running SpeedFan and it recognized the 7600 card just fine, however it's not recognizing the 5770...Pretty sure i've got the latest drivers installed. It shows up fine in Device Manager.
One other thing, the text on any screen seems a bit blurry as well... not crystal clear like I figured it'd be with this kind of upgrade.
