Windows 7: Crossfire'd 5970 - $600 good value?

Windows 7 x64

In that case my original suggestion of going with the current top shelf from either nvidia or ati should do very well.

I'm actually on a single 580gtx right now, I have honestly never been as happy with a single card.

Well waaaaay wayy back when I first go my old ati 9800 AIW PRO ... that was pretty awesome too graphics cards were completely different back then though.

Roughly. 2nd hand 5970's are going for around $250. Maybe a little more with the block.

When I sold my 5970 I bought a 580 and it was the best move I'd made. What I lost in raw FPS, I made up for in overall smoother game play.

No doubt a 5970 is an improvement over a 5850 (you could even tri-fire the 5970 with your existing 5850). However it all boils down to driver support.

I haven't been following the current state of CAT drivers, especially support for 5970's - but for titles that don't 'play nice' with CF, AMD's fix is to disable CF which means you'll be running off a single core (basically 5850/5870 speeds depending on OC).

As mentioned you'd get the same performance from a 680 as a single 5970. Even an OC'ed 670. Plus you wouldn't have to swap out PSUs. (If quad fired)
(I personally don't think the extra price for the 680 is worth the minor performance increase over the 670)

You could probably SLI two 670s off your current PSU. Seasonic is a quality unit - 650W would be cutting it close, but doable. It's $200+ more than the $600 deal, but you'd get shit hot performance.

At ~$400, a single 670 would be a very noticeable upgrade. No need to swap PSU.

$ 600 deal, great performance - when supported - but will require new PSU if going Quad fire. ~1000W for quad.

$~800 670 SLI. Great Performance. Generally better drivers. "May be able to keep current PSU". (although if you're looking to OC, add a watter loop etc, a new 750W-850W PSU would be preferable.

Basically, which ever way you go - you're getting a performance increase.

Thanks, i did read somewhere that the Nvidia 670 (and maybe the 680?) is quite a bit more energy efficient than the current equivalent AMD offerings.

If i can keep my Seasonic 650 and get a 670 i'd be very pleased i think.

Would that still apply for overclocking/water cooling? Would i then have to up the PSU anyway?
