5870 vs 4870X2
 

I have the chance to pick up a used 5870 for about $150 and I was wondering what, if any performance differances I would see from my 4870X2.From what I've read probably nothing spectacular.I would like some opinons from somebody who made a recent switch to a 5870 from 4870X2 or if I should bite the bullet and go to a 6970

I went from a 4870X2 to a 5850. (Ok there was a pair of 4770's for a few months between the two). It's cooler, just as fast when OC'd, none of the annoyances of Crossfire, DX11. But going up to a 69 series might be a good idea.

At that price, definitely worth it. You can sell your 4870x2 for around that much on here. Less power, quieter, more OC headroom and Dx11.

as per above, dont think about 5 series when the 6950 2gb can be had for a couple bucks more

get a 6950. there will be barely any performance benefits from a 5870, and actually in some cases the 4870x2 does perform better then the 5870. only thing you will notice with the 5870 is dx11, lower wattage and less heat/noise depending on your case. get a 6950 imo, it will be a good card for a long time still
