Be interesting to see as my Quad definately was holding back the 4870x2 Quadfire, whereas they flew on an i7 rig. Just possibly something for peeps to consider before they jump in with both feet

5870's in crossfire.

I would go with the i7 series, the 920 is a great overclocker when given the chance and will serve you well
Fast (3ghz+) Phenom 2s, Core i5s or Core i7s.
Probably not worth it for you to upgrade, but a single GPU solution is far better than Crossfire.
Looking at reviews i7 seems to perform about 15% faster clock for clock in games. So a Core 2 Quad @ 3.45+ should also be fine.
I need a new cooler

Thinking about it, that Vantage score doesn't mean much, we need to see the Vantage 'extreme' numbers with these cards.

ok i'm wondering whether i should get just 1 5870 as an upgrade from my 2 8800 GT's, or 2 5870's.
if i get 1 5870 i could sell it if anything better comes out in the next 6 months.. if i had 2 5870's it would have to last at least a year or 2.
firstly im guessing a single 5870 should be a good 80% better than what i have now but not too certain, it has to be a pretty big difference or i wont bother.
what would you lot do?

Single 5870X2
It won't be, two 5870's will be better than one 5870x2 in performance, same as two 4870s's in crossfire out perform a 4870x2.

I've got a Q6600 @ 2.4GHz as well, total fail in overclock, it was mega unstable, and for me I need rock-solidness for my work. I'll see how the new ATI card (or Nvidia if they get a move on) goes with it @2.4GHz and decide from there.
are you sure? my Q6600 is running 3.4ghz stable all day long, I used other people Q6600 OCing setup.

Not totally sure, but stability was important. As I said, I will see how it goes with the AMD 5870, and if it's really limiting then I will try an overclock again, or get a new machine.
I only tried something like a modest 2.5 and 2.6GHz and it wouldn't stay stable. Machine must be bullet-proof stable though for my work...

You can easily get nearly all Q6600s to 3.4-3.6GHz "bullet-proof stable".

If a Q6600 wasn't stable at 2.6Ghz then, without sounding like I'm having a go at you, you're doing something wrong with overclocking it.

anything under 3.2ghz will limit your system even if you've a hign end graphic card.
My crossfire 4890 doesnt even operate at its full potential because my pci-e will only run at 8x in crossfire= (
I will actually lose 10 frames in Arma 2 if my Q6600 run at stock

Going by 4870 there's is often not very much in it, in some instances also depending on the motherboard the onboard pci-e bridge does give an advantage.
