You fancy some new toys with those great 7950s. Spare a thought for the guy with a 8600GT![]()
No good trying to talk me out of it mate.
Pick a card, any card. (from the ones listed above that is)
If not watercooling then I think you only have two options, I am disregarding the caveats in OP.
1) 7990 for quadfire with your 7950s
2) wait for a 290 pro with proper cooler![]()
You should definitely upgrade seeing as you only have one 670. You'll get more than double the fps!
I know but i need a change. Its hard to explain but i need a new toy to play with, to benchmark etc. I also quite like the idea of only using one PCI-E slot on my motherboard.
Thought spared.
Now why don't you buy them off me?![]()

290X for me Matt (been pondering it myself tbh), 7990 too much of a side grade (and I think Mantle will shine a little more brightly on the newer architecture)
7990 will only do quadfire with another 7990 and trifire only with a 7970 afaik
You can quadfire a 7990 with a a 7950. If i go that route i will test it.
As always the price vs performance on Nvidia cards means i won't consider them. However the main factor is Battlefield 4. I will put a thousand hours or more into this game and to get the most performance possible from it ill need an AMD card and Mantle.

Wow, I expected PCI-E 1.0 to be much lower.
Loving your faith in Mantle...I hope it is living up to the hype that people have given it.
keep up to a good workFirst set of results
2 x R9 290Xs @1200/1625 PCI-E x16/x16
3970X @4.0 (low overclock to put more stress on PCI-E lanes)

Going to test now with bigger overclock on CPU
I was searching about it on google recently I believe a 7990 can only tri/quadfire with another Tahiti XT GPU not a Tahiti Pro one.
I would say go for a 290/X because of the top performance for the money but do you not think you might wish you waited if a IceQ 290 came out next month?
RE: PCI-E 2, I am in the same predicament but a 3770K will unlock PCI-E 3 on my mobo. I imagine yours too. So if necessary that is a simple drop-in upgrade rather than buying whole new system.
My blocks are coming tomorrow so I will see if I saturate PCI-E 2 8x/8x with 2 290s.![]()

x16, aka PCI-E 2 x8.
Is no one going to press a claim for a 7990? Come on 7990 users make a claim for your card. I've been looking at reviews and at 1440p it trumps every card out there, including a 690 which is also a great card.
