LIke everyone says,
Your best options are, 1. Go tri-crossfire 6990+6970 = better than dual 6990's in terms of actual gaming/compatibility/less stuttering etc. B. Sell both and get just 1 7970 as its enough for most people. Or sell everything and get 2 gtx480's for around $500 and be happy with Nvidia as I am smile.gif

2x 480s would be a serious downgrade compared to a 6990:
Higher power consumption
More noise
Less performance
Less VRAM

Please don't buy 2x GTX480 as someone suggested you OP, unless you want to make your comp into a heater for spring. I would say sell your 6990 while it's still in its top $$ and buy a 7970. There is very minimal next to none stuttering for 7970 CF, some people here posting stuffs without using their brains or facts.

Why is your CPU only at 3.3ghz?

4 GPUs? That's crazy, no CPU will free you from the bottleneck.
2 7970 is way better, cooler and economic.

Thanks all, appreciate your help in advance! smile.gif

+1 6970. it's the cheapest option for you, and will give you good performance.

To sell a 6990 then buy 2 7970.... too much $$ for smaller gains, plus too much trouble.

Just grab the 6970 and tri fire them. no pain, a lot of gain biggrin.gif

Have fun


EDIT: he said power consumption isn't an issue, folks.

I wouldn't get another 6990, go for Tr-Fire 6990+6970 that will give a nice boost in performance for the lowest price. I would use this configuration for a few more months until the 7970's start to work out their bugs and we get a few more highly overclockable variants like the Toxic's. If you are going to switch to 7970's they need to be very good overclockers to beat Trifire 6990+6970.

You can get a used 6970 for $300 and it's all good or spend $1200+ on 7970's seems like an easy choice to me. wink.gif

Actually you can get used 6970s for 250 all day long these days, and used 6950 2GBs that are pre-unlocked or unlockable for as low as $210. It's the best time to be an AMD (ATI) fan right now.

Personally, my 3 6970s can run BF3 in eyefinity @ 5760x1080 @ 60fps avg w/2x MSAA on Ultra, and ~120fps+ @ 1080p maxed on my 120hz monitor, and their score is dead even with 2 7970s in 3dmark, so I'd view them as better bang for the buck right now, but if you're looking for more VRAM and less cards/power consumption/decibels, then sure go for the 7970s. Honestly, if you're going to go that route, save a couple hundred bucks and get 2 7950s, do the BIOS trick people have been doing, and OC them up, and you'll be blowing away stock 7970 CF rigs all day long wink.gif
