Default crossfire 4850's vs. single 5850

Hey guys...

I currently have one 4850 in my system and a psu that could handle another. Should I pick up another 4850 for 100$ or sell my current 4850 and put down another 200$ ish for a single 5850?

If this helps I'm using socket 775 (e8400 @ 3.6ghz)

Is dx11 really that worth an extra 200$ for the same performance?

Thanks in advance

xfire do not double the performance in every game, I just plug my 5870 in xfire, in stalker bench... I increase the maximum FPS. but the minimum one rest the same, nad it's the minimum FPS I have to increase..

yes I will sell the 4850 and get a 5850 ... more game will come with directx 11, don't spent in old technology a side the 5850 will cost you $ 200 more ..but an other 4850 is not free, so let say you find one at $ 100 it make the 5850 option only $ 100 more not $ 200

I'm already counting in the money I could get for my original 4850 in that 200$ more price. I could probably on get like 75$ for it anyways.

I think the 5850 would be a much better choice.

5850 is the better option unless:
1. You get a great deal on a 4850 (I would say $100ish or less)
2. The games you play scale decently with crossfire.

Few things;
First, 4850 Crossfire scaling was terrible. It's generally just better to go for a new card.
Second, as was mentioned, 4850s are an old technology and probably not worth investing in.
Third, where are you getting the information that Crossfired 4850s = 5850. I'm very skeptical of that, knowing the 5850's performance and the 4850's infamous scaling. I would expect a 5850 to perform better than 2 x 4850s.

There is, of course, another option; you could sell your 4850 and get a 5770. You'd get a nice FPS increase in every game I can think of, and, if you still need more, the scaling is off the charts (I've heard of benefits in excess of 100%...god knows how, but I'm pleased nonetheless). There seems to be a general consensus that the best price / performance you can get is 2 x 5770s, at least as far as I've seen (costs under $350 and performs about as well as 5870). Anyway, the great thing about this plan is it allows you to get a good FPS increase now without breaking the bank, as well as a very large one when you have the budget and need for it.

look at the diffeence betwen x fire and single 5870 in Stalker CoP with direct x11, the minimum do not change too much, and the problem for me is the mimimum , I came back with the 4890 vs 5870 in directx 10

single


xfire

+1 For this! A single 5770 performs around the level of a 4870 on raw strength, but you get the added bonus of DX11, native HDMI, and rediculous XFire scaling should you pick up another one.

direct x 10 look at the gain of performance in the minimum FPS , when pass from 4890 to 5870 , it is far more than the one we see with xfire the same card

4890





5870

Crossfire can be a pain.
