I wonder, if i bought one to go with my 5970, wouldn't i still be stuck with 1gb total memory per core.

Yes you would still have 1gb per core. That's how crossfire / sli works. Each gpu needs an identical amount of memory to itself for rendering frames.

I'm also not 100% sure you can tri-fire a 5850 with the 5970 :confused:

I've seen people use a 5870 with the 5970 in tri-fire - the 5970 is 2 downclocked 5870 gpu's iirc - but not a 5850.

Im just wondering of the 5850 will reduce the memory bottleneck the 5970 has when pushed?

If you need more vram then sell the 5970 & add the cash you were going to spend on a 5850 and get a 6990.

Or, if your motherboard has 2 well spaced pci-e slots so the cards get good airflow, buy 2 6950's instead and pocket the £50-70 saving compared to the cost of a 6990.
 
AWWWWWWWWWWWWWWW i've just ordered:

one of these 5850's ( to go with my other xfx 5850 )
an 850w xfx psu ( my 600w needs upgrading )
64GB SSD
1TB samsung f3......

god help me, my wallet is sunk

what brand is your psu and the spec of the rest of your rig . you might be pushing it but it might be poss if you have a quality psu

My SD37P2 with the 450W version of the PC55 PSU could run an XFX HD5850 1GB Black Edition at 840MHZ for the GPU and 1125MHZ for the RAM and a Q6600 overclocked to 2.67GHZ fine. However,my card has the reference cooler meaning most of the hot air is vented out of the case.

I also know someone on another forum who said that they can run an HD6870 1GB off a Shuttle 400W PSU.

Cheers chaps

Mines an old C2D based SD37P2 and the PS used to run 2 of the old 1950XTX's in XFire although the PS fan used to wind up a bit under load. I was saving the pennies for a 6850 but I think I may take a gamble with one of these 5850s.
 
I keep coming back here wanting to buy the Titan Megalosaur and I'm sure I will in the coming month, question is having seen Anandtech's benchmarks, a crossfire setup of 5850's seem to do much better than a single 2GB 6950 as shown.

What the benchmark doesn't show is the power consumption or heat levels. Surely spending an extra £15 to get the crossfire 5850's over a single 6950 is a good deal right?

i've got 5850 in crossfire set up, and it works good now i've set it up rite!.
you will notice a lot from adding another 5850 into your system.
 
Hmmm tempting, might go down the 6990 route.

Though im sure you can flash a 5850 to a 5870?

Would the 5850 be a worthwhile upgrate over a GTX 285. I could probably get £90 ish 2nd hand for my Nvidia?

I'm pretty sure your HD5970 is the 2GB version in which case it uses 1GB RAM per core anyway.

Crossfire will divide load between all 3 cores so all you need to do is set clocks for both cards accordingly.

You can't unlock 5850, no. You can flash with a 5870's BIOS but all it does is increase in clock speeds (which you're better off doing manually anyway).
