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.
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.
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.
