Windows 7: Debating on upgrading to Radeon HD 6870

Debating on upgrading to Radeon HD 6870

Specifically, I'm looking at buying this. Currently I have a PowerColor Radeon HD 4890. Would I notice any significant performance increase by buying this?

To soon for 6000 series cards. You would see better results going with a 5000 card right now. Price is kind of weird too. 5000 cards cost more then 6000 cards for no apparent reason. Still your money is better spent on a 5000 series right now.

I'll probably wait a year and see what's out then. I might be better off with that because the Radeon HD 4890 cost me about $200 and runs almost every game I throw at it at max detail without lag. Temps aren't horrible either. Under load it seems to run at around 50 C.

I might also buy a Radeon HD 4870 x2 and Crossfire it with the 4890. I've heard that this is possible because the two cards are essentially the same architecture. I've seen 4870 x2s on eBay for $110 - $200 in great condition.

Check again. There's nothing wrong with the pricing actually.

HD 5850's are now in the low $200's (~$220 IIRC), while the more powerful HD 6870 can be found for as low as ~$250.

And to the OP, how much are you willing to spend?

EDIT: a HD 6870 would be ~25% faster than a HD 4890.

You'd probably get better mileage out of another 4890 instead. Slightly less headaches.

Cat drivers and the 4870x2 haven't been getting along to well for quite a while now. (2nd GPU 3D clock issues) It's not a priority series, let alone card that gets much attention now.

Plus Tri-Fire scaling is pretty poor and bugger all games will show much improvement.

As a proud owner of a 6870 i can tell you it rates right up there with the 5870 it is slightly slower by 7 to 8 points in benchmarking

besides that 6870 has eyespeed technology check out the scores between the 5770 and the 6870 this should give you a idea of what it is like

a reduction in temperature as well, I notice..

will 2 6870's run in crossfire - I can't find confirmation of this..?

even though the GFX cards look as though they have the crossfire tabs
the XFX version appears to indicate that crossfire is not an option (- via their site)..

- odd?

I recently purchased a sapphire 6870, I'm very happy with it, for price-performance ratio its the best. Drivers seem to be s*** at the moment though - cant use more than 8x anti aliasing while the card supports 24x and a few more minor issues. Demanding games such as Metro 2033, AvP or crysis all work smooth on maximum settings.

I don't exactly understand ATI's new cards. according to CPU mag, they are slower than the 5 series. Sounds kind of bass ackwards to me...

ATI drivers are ALWAYS that way off the bat. They take time to get them dialed in.

There are plenty of vids on youtube showing it.
