So I'd like to add a second R9 290 to my rig for crossfire. It is questionable if my power supply will cut it (Corsair 750TXV2) but I know how to resolve that.

I currently have the Asus R9 290 Direct CU II. Right now this card is at a premium, although not the premium that I bought the first one at.

You guys think I would be okay going with a second card that has similar specs but not necessarily the exact card?

I don't have any windows on the side of my case so I am not worried about it looking like Frankenstein in there.

Thanks in Advance!

yes, you can mix any kind of brand to Crossfire, even you can crossfire it with a 290X.. so you will be fine with any brand and model, just you have to keep an eye in the Temperatures to avoid throttling..

in the other hand, you will be in the bare minimum system requirement to Xfire with 290.. and overclocking will be prohibitive for you.. I would use at least a quality 850W PSU for that setup..
 
I was thinking more of another R9 290, but not necessarily a Asus Direct CU II.

Heat isn't a problem, I have plenty of cooling and already am running one of the coolest R9 290s.

I am not planning on OCing the GPUs. I was looking at 850s but if I am gonna make an investment, shouldn't I go up to a 1000W minimum?
 
yes that's one of the coolest 290s, but any aftermarket cooled card dump all the heat inside your case, and if you have Crossfired/SLI'd Before you should know how dramatically can increase the temperatures inside a case with aftermarket cooled cards, to the point people prefer to use reference cooled 290 and 290X to crossfire due that fact..

two weeks ago I was testing Xfire with 280X and even in my case (Corsair C70 fully of NF-P12s and SP120 fans) with amazing airflow, temps was always a concern with 290s and 290Xs things can only go worse.. and yes, if you are planning in make a investment in a new PSU try to find a deal in a high quality 860~1000W PSU..

but to keep the point in this thread, yes you can use any other R9 290 for Crossfire without issues.
