Not sure if this will work? advice needed.

Hi all. Haven't been on here for ages but wouldn't ask any other forum. In my current rig I have an i5 2500k with 16gb 1600 ram and a sapphire 7950 3gb oc with boost.
My question is I've always wanted to try crossfire out. I'm just curious about it. I've read that I can crossfire a Tahiti 7870 with my card.
Will it run and still have the 3gb vram or will it down scale and only use 2gb vram? I can't find any benchmarks for this crossfire setup. Any links to any benchmarks would be most appreciated.

Thanks in advance
Steve

Yes it will work, but you will be limited to 2GB.

You can only crossfire it with the 7870 LE.
I'd just get an R9 280/7950 though.

Considering the price of a second hand 7950, why would you go for the tahiti 7870? I've seen both a vapor-x and a WF3 for ~110 posted.

I've seen the price. I actually got my 7950 for 90 free postage on eBay. I was just curious as if I could get a great performance with not quite as much power consumption as 2x 7950s. So will the r9 280 crossfire with the 7950 fine?
I do want to try crossfire as I'm sure most "next gen" games coming out will support it and from what I've read and seen the drivers are getting a lot better as they do with the demand of new setups and technology. I don't want to spend to much and I'm watching a Tahiti 7870 that's currently at 29.99. Sometimes you get a bargain with auctions and you never know. Lol

I would look for another 7950, ive tried mixing cards in the past and whilst it worked results were never as good as using the same cards
