more performance which root?

[smogsy]

want more FPS in BF4.

Running at 2560x1080 70fps All Ultra except AA, dropds in shanghai to 55
i have:
i7 3770k @ 4.2 [ 4.6 gives me no extra fps]
16GB 1600Mhz
R9 280X Vapor OC
Bunch of SSD/HDD

280X is 2 weeks old if that [rma from a 7970]
Overclockers Owe me 280 pounds from RMA as i bought the 280x for a faster RMA turnaround

so do i:

1. upgrade to 280x xfire? < this one would less likely now due to case space..

2. get a 7990? [ sell 280x]

3 get a 290x [ sell 280x]

4 get a 780ti [ sell 280x]

5. hope mantles good?

my board mpower z77 runs 2 cards at x8 3.0 pci-e

should not lose to much performance from that?

 

[smogsy]

so after reading your post & doing a Measure up.

My Soundcard [Xonar STX] would be very tightly packed in. next to these cards so i think that's a no go...

so that leaves

7990 vs 290x? what should i choose?

 

[smogsy]

looks like a tough choice.

it looks like this to me:
7990
- faster but Xfire, Could be slow in other games with no profile
- Could Get Hotter, but comes with a decent cooler
- Old Tech Could stop Support eariler than the 290x but Its not Old yet

290X
- slower than 7990
- Reference cooler is appealing (less heat in case) but hotter card possibly noiser
- could possibly fit 2x reference cards in my case + my sound card
- can upgrade to Xfire Later

 

[smogsy]

really tough

although with the 290x you can limit the temps to say 70c and it downclock not to go over this, this is correct?

not that im going to but its a extra feature
