Supplying my Crossfire Cards

[Isaac3104]

I am planning on upgrading my current rig from one Sapphire Radeon HD 7770 Vapor-X to two Sapphire Radeon HD 7770 Vapor-X crossfired. I was wondering if you guys could help me out on picking out the hardware to support it. My current rig just isn't cutting the mustard and I don't want to buy a whole new graphics card and trash my 7770. My wish list for the items I have chosen are listed below. I would like to know if these items will fit, power, and hold these two cards crossfired. If you have any suggestions on what to upgrade to please suggest them. I am on a limited budget of $500-550.

The wish list looks fine, but I would increase the size of the PSU. 2 x HD 7770s aren't all that power demanding, but it would be better to have something in the 700W - 750W range... especially if you ever want to replace those cards with something a bit faster.

But I gotta warn you... two mid range AMD cards (in CF) are going to be a problem when it comes to micro-stutter. Some folks aren't bothered by M-S, but a lot are. Personally, I would avoid a 2nd HD 7770. You can always sell the one card on ebay or someplace and recoup some of the cost of a single faster card.

The good news is that AMD is promising to provide an "anti-microstutter" driver soon.

Alright thank you. Is there a good PSU that's not extremely expensive, but not a low end Apevia that will hurt your system?

Did you change something in your wish list, or did I just mis-read it last time? The PSU in the list now is a 750W Corsair, and I swear it was a 650W last time. Anyway... That Corsair 750 is a great PSU. Go with it.

Uh yes I realized I need a little more Wattage to be able to overclock these two cards. A small amount of room of my budget has opened up and thought I will need better psu.
