Was holding out for the 69XX series but from what I can see in the reviews bang for buck CF 6850s are where its at

Am currently running an overclocked 4870 1gb with a E8500 @ 4ghz with 1600mhz DDR3 ram

Was hopeing to get another year or so out of the CPU before I went a whole new sandy bridge setup

Was wondering if the E8500 is going to be a major bottelneck with these 2 cards?

Games I play are @ 1920 x 1080 and I like the eye candy turned to full or as high as I can crank it and get ok FPS

Titels I play/ want to

Modern warefare 2
Fallout new vegas
Hawx 2
Bad company 2
Starcraft 2

Wondering if anyone has tried out the E8500 with CF 6850s

Cheers

I guess not, your system is still fast enough even for today's standard.
2 Cores CPU at 4.0GHz is already fast enough and no, you won't have problem running dual HD6850 with that setup. :)

Ofc, quad will be better- but E8500 at 4ghz will do fine-

The resolution you play mostly benefits from GPU and is less dependable on CPU, so as posters above mentioned,you'll be fine.

Good to hear that the old girl still has some life in her yet, got to love 3mb of cache per core :)

Oh one more thing to throw into the works, at the moment I can pick up factory oc 5850s for $246 each so thats $492 for the pair

otherwise factory oc 6850s are $226 each so $452 for the pair

Just so you all know im in Australia and we seem to pay more than those of you in the US even though our $ is pretty much the same @ the moment

One other thing to considor my PSU is is a Thermaltake 750W

at the moment my 4870 heats up my room like an oven in summer, im guessing that a pair of the 6850s is going to run cooler than a pair of 5850s

Im thinking that a single 5850 should beat single 6850, but it seems that the 6850s scale a lot better than the older 5850s in CF which is why im thinking that the 6850s may be a better choice?

^^ Yes, true to all you said-
But to mention 5850 is a bit faster than 6850..
6850 is newer generation, more efficient, cooler than 5850, i would go for 6850 over 5850..

On a side note 6870s go for around $290 - 350+ down here

I figure the overclocking headroom/price of the 6850 makes up and then some for the performance gain of the 6870 when ill be paying at least $128 more for 6870s without that much gain if the 6850s oced

Yes,OC'ng the 6850 will give you roughly the same performance of 6870(with a good cooler)

Ill be going the Gigabyte 6850 which has a pretty sweet cooler setup, dont know if ill crack the 1ghz but 900 should still be sweet enough particually when running 2 of them in crossfire.

malmental im going ATI cus my board only supports CF not sli, Nvidia 460 starts @ $188 and goes up to $296

Best prices in AUS for hardware are usualy gamedude.com.au or umart.com.au I usualy go to Umart as they are closer to where I live
