If price is an important factor -as it appears to be- then wait a bit for October .. HD9000 Series will be launched then you can get much better prices .. You'll have the choice either to pick on the new 9xxx cards or just CFX your existing with better price ..

That makes the combo $500 while a pair of reference 7870s can be had for $350-400. For $100-150 in savings I'd still side with the 7870s.

But I also really, really like my 7870s, so I'm a little biased. :)

I'm still getting a second 7870, but I'm just looking at the actual price to performance ratio

It'd be interesting to see some graphs of SLI 7870s vs SLI GTX 760s. Currently though, I side with the 7870s. That $100 savings can be put to a lot of other useful things.

You can keep a gaming setup under 1K with the 7870s (with a 4670k or 4770k) but I don't think you really could with the GTX 760s (especially at $500 a pair).

I'd really like to see a review and a price to performance ratio pitting the two against each other.

They have a review with 2x HD 7870s, 2x 660 Ti's, and 2x HD 7950s

it would be cool if anandtech had an option for their benchmarks to sli or crossfire the gpus

I'm running 2x SAPPHIRE Radeon HD 7970 3GB crossfire. Did benchmark with Tomb Raider.

Considering the fact that your results are very close to what you'd get with an upgraded Mobo, I'd wait to upgrade your mobo for a year and do it as a platform upgrade with your CPU.

Ivybridge and Haswell were lackluster, whatever comes next HAS to be better at this point... doesn't it.... please?

As lackluster as Haswell was, it's still a few generations ahead of the 8320 when it comes to pushing VCs in gaming.

I wouldn't spend anymore money on AMD (meaning motherboard upgrade).

Your platform is holding you back at this point imo.

Anyways not bad, on your 3DMark11 run. This is what I get with two 7950s.

Its not only to get a second x16 slot but also to achieve better overclocks on my CPU as my current board only has 6+2 PowerPhase

And why would you think 6+2 phases arent enough to push that 8320 higher? Quantity doesnt always mean quality, specially in vrm design.

Because 6+2 can't delevrythe power needed to a highly OC'd FX 8core

It does if you have good VRM heatsinks and case airflow. My FX-6300 is at 4.0 GHZ on a 4 + 1 board (1.31V) and I can easily leave my fingers on the VRMs indefinitely without burning them. That tells me that they are well below the thermal limit. What voltage are you at right now?

I'm not trying to discourage a board upgrade--do it if you want to--but I'm not convinced it's actually necessary in your case. Have you tried OCing the northbridge or raising the FSB while lowering the multiplier to squeeze out a little more performance?

But you have to remember i have two more cores than you and power consumption can easily go past the motherboards rated 140w. If i go above 1.45v PC won't even boot an i also have a 140mm fan blowing on the VRM heatsink

I dont think that should be blamed to the vrms. You know when you are short on vrm juice whe you load the cpu with a stress test at a presumed high vcore and your over current protection system(built in your motherboard) makes your pc shutdown.

I tell you because i have the very same mb paired with a ph x6 and it ran at stupidly high stock vcores(lots of mb need to have stock vcore on these procs corrected) and it ran just fine

And considered that x6 actually can draw even more power than 83xx's when you raise the voltage. There is a review of this mobo where it showed it could withstand up to 275w of power draw before the current protection mechanism kicked in
