i currently have a 4870x2, starting to lack in a couple of games, thinking a cheap upgrade would be to just grab another 4870 1gb and throw that in, but my main question is, would it make it support eyefinity at all?
 
No eyefinity from what I can gather that is only 5 series and above. The extra GPU will help in some games if coded for it or driver profiles from AMD. If your games are lagging due to ram limitations however it really wont help much. Run GPUZ and see if the gfx cores or the VRAM is being maxed. if its just the VRAM, forget it tbh, If it's a bit of both probably worth picking up for the price of £35ish and it could be cool to play with :)

EDIT: oh and run GPUZ with some kind of frame limiter or vsync enabled.
 
vram seems fine tbh, 1.7gb usage, max and thats in BF3 which i didnt like too well (its 1gb per core so its loaded in twice)

main games atm is dirt 2 / dirt 3 / other racing games of similar, dont really see much over 1gb total ram usage so i think its just raw power its lacking, its hard to judge because all reviews are using catalyst drivers that are years older than current, and going from 9.x to whatever latest is, i have seen better performance from my single 4870x2
 
I'd grab another one then, scaling on the 3rd GPU is usually a fair bit less than the second but still worth it. Not sure if this holds up with the 4 series but I believe it's fairly good.
 
Hardly, but maybe if you are on PCIE 1.0 and both move down to x8, your x2 would then have x4 per card, If it's PCIE 2.0 don't even worry about it at all. I had a look around and you should be looking at around a 30% increase over your existing 4870x2

This is your mobo however and as its a 890 series you should have PCIE 2.0, I do on my 790 series. http://www.gigabyte.com/products/product-page.aspx?pid=3785#sp
 
going tri fire with the 4870's does realy god things for your minimum FPS tripels it in some cases from what i read when i was looking at it like 7-21 fps

oh btw your 4870's will only have 1gb vram each
