CF 7950 or CF 7970

post #1 of 8
Thread Starter 
Okay, I'm about to finally be able to build my dream machine. I was just curious if you guys would go with CF 7950's or CF 7970's. I was think the 50's only because it will be $200 cheaper. Also, what do you guys suggest for power supply for CF these both, like how many watts?

A quality 1000W PSU will be plenty for those cards. There's been pretty good stats for overclocking on the 7950's up to 7970 clocks but really up to your budget. Overall I say that Xfire 7950's are pretty much gonna be able to run anything you throw at it for a good while. If you have the budget since you said this is your dream machine you might as well spring for the 7970's.

You could save some money by getting the 7950s and get performance that's fairly similar to the 7970s when OC'd along with a nice 850w power supply.

OC them to 1200MHz if possible and run circles around everything on the field including my 580s. frown.gif

7950s, a quality 750w is more than enough to run your system with plenty of headroom. The tdp on the 7950s is actually pretty low (lower than 580s) for the performance you get.

A Seasonic X650 will run your cards just fine.

So looks like the CF 7950's will do it. You think a 850 corsair will be good. Any suggestions on which one will be good?

Seasonic x650 or x750
Corsair hx650, hx750, ax750, tx750
Antec neo eco 620w
Xfx core 750

All will power it just fine
