7990 or 290 Crossfire, which would you choose?

Have you tried quadfire on BF4 yet, both DX11 and Mantle work very well with it.

The latest drivers have some good improvements for 4 way setups, Crysis 3 is another game that works well.

Here is another bench I just ran using quadire I have just posted in another thread.

Just messing around hence the low CPU clockspeed and this popped out.

4 x 290Xs @1230/1500

4930k @4.0

Wait, quad fire works in Mantle now under 14.6? That's good news. :cool:
 
Shame that quadfire doesnt work.

In the x295 reviews quadfire doesn't scale well with 2 of those either. But in trifire it is very good.

You have loads of cards it seems, you dont have a 7970 lying about to try trifire with one 7990?

If it were me I'd go for 2 or 3 (as you have them) 290's. That extra RAM. Depends what fps at what resolution you want or hz. I'd imagine 2 x 290's would be plenty for whatyou want and whack in the 3rd for when you go 4k.

I'm gonna get the x295 when it drops a bit and get a 290 later to boost fps for 4k.

Hope you made your money back on mining.

Quadfire also works very well in Crysis 3 and BF4 but these games don't have built in benchmarks to test.

Thief will be fantastic with Quadfire on a 4K monitor as it scales very well too if the resolution is high enough.

Have tried. Quadfire with my 4770k at 4.5GHz and the system chugs along at 30-40fps in Battlefield 4. Thats with both Mantle and DX11 so something must be up with my setup.

You have 2 7990s with a 8320? Disgusting :P
Click to expand...

The 8320 was bought as I fancied having both an AMD and Intel setup. Originally the 8320 was used with my 7990s but since then i've bought a 4770k so switched the systems around.

The three 290s and the 8320 were my work system and the 290s were just mining 24/7 hence we wondering what would offer the better performance.

290's for performance and the 7990's for E-peen
Click to expand...

The 7990s are gorgeous but i'm after performance here!

I drained my loop last night and have taken the 7990s out and replaced them with 2 290s, with the third sitting next to me.

Will do some testing later
