Does anyone know how well the XFX R9 280 can handle games at 1080p using a 3 monitor Eyefinity setup? I plan on investing in another monitor, so I'm wondering if it's worth buying two more and trying Eyefinity.

I f you read through some of the benchmarks you can see how the card will scale and it will give you a good idea of the cards frame rate at different resolutions,
http://www.bit-tech.net/hardware/graphics/2014/05/19/am...

with eyefinity being approxamately two steps past 2560x1440, ie 1920x1080= 2M pixels , 2560x1440= 3.7M pixels, 5760*1080=6.2M (eyefinity)) you can see that your framerate would dip well below acceptable (likely down ~10-15, if 3gb is sufficient Vram for that game) on ultra, however you may be able to compromise you settings (to med/high) and get back up to atleast 30 fps

OR you could invest in a second 280. but all told, i wouldnt recommend eyefinity on your card

Would overclocking help at all? If I could squeeze 30 fps out of med settings, I would be okay. Eyefinity wasn't my plan when going building this budget PC, so any use of eyefinity would be a bonus.

Overclocking a gpu tends to produce an additional few fps during gaming but not generally more than an increase of ~10% ie 30fps ->33fps etc. I have sen some people getting playabe experiences on med/high is some slightly older games (battlefield 3) with 7970's (about equivalent to a 280x) , but you should consider if all these compromises to play eyefinty at barely 30fps its worth the cost of the aditional monitors
