Radeon 4850 CF vs Used 4870x2

Hello, I'm looking for some opinions here.
I'm not sure if I should go with the
Radeon 2x 4850 in Crossfire and Asrock Extreme3 870 mobo = 970zł (320 USD)
OR Used Radeon 4870 x2 with Gigabyte mobo = 1020 zł (340 USD)

The difference in price is negligible, the Radeon 4870x2 is the Palit factory OC'd version with a thicker PCB and two fans. According to the auction it was bought in january 2010 and it's pretty much in perfect condition. I'll pair these up with an Athlon II x3 440. I'll try to overclockit as high as possible, stock HS for now though. My monitor resolution will be 1080p.

Which GPU would you suggest? I'm not intrested in any fermis. Only looking for the best bang/buck.

Hello
If the 4870X2 is in perfect condition,then go for it,its worth the extra $20

Thanks for the reply, what about heat or power consumption issues though? Will it run hotter than the 4850's and will a 600W Stealthxstream suffice for powering the 4870x2 while overclocked?

The HD4870x2 overclocked consumes 470W, so there would very little for the other to use. I would say it would be better if you go for a bigger PSU.

Where did you get that number from? The HD4870x2 tends to use about 270w under load during normal gaming. I suspect the number you saw was for the entire system, not the card by itself.

Also if I decided to try and overclock a bit only on stock cooling, would the difference between the radeon 4850x2 and 4870x2 become negligable because of the Athlon II x3 445? If so what kind of budget CPU heatsink would you guys recommend? I'd guess that a small OC around 3.5GHz would remove a noticeable bottleneck at 1080p.

My mishtake! :( 

Yes it was for the complete system.
Then i think the OP is fine with the PSU.

BTW, ft it from here:

and another from xbit and pcstats.

This is the card he is likely talking about;
http://www.guru3d.com/article/palit-revolution-700-delu...
They have the entire system using 429w under full load. The 600w StealthXStream claims to have 580w on the +12v rail. It should handle the card easily.

From what I've seen on this one review the OCZ Stealthxstream 2 600w has 18A on each of it's 4 12v rails. This should suffice right?

Well thanks for the replies, I can't find any viable heatsink other than the Hyper 212+ It should be a great buy at the $30 they're selling it for.

"the Radeon 4870x2 is the Palit factory OC'd version with a thicker PCB and two fans"

and it comes with a better motherboard?


Who cares if it is second hand, at least you know it works (hopefully).

I just wanted to mention that as the 4870x2 tends to run hot from other manufacturers.

Why didn't you think about getting newer cards? And why aren't you considering fermi?

The GTX 470 is almost as fast as 4870 X2 while consuming less power and costing less, add to that DX11, CUDA and physX.
GTX 460 is an excellent mainstream card, although not as powerful as the options you listed.
GTX 460 SLI is a very powerful option (although more expensive than the cards you listed).
HD 5850 is a little slower than 4870 X2 but cheaper, consumes less power, and has all 5000 series features.
HD 5870 is equal to 4870 X2 in performance but a lot better in features and power consumption (although it is more expensive).

So there are really good options among DX 11 cards that are worth considering.

He is in Poland. Card availability and pricing is not the same as in the US. That said a more power efficient and DX11 compatible card would be a nice if you have the option.
