I was just thinking... Would a 6GB 7990 For 400-420 be a valid option ? Else I thought about 280X 6GB... Same price. I was just wondering which one would be the best. I thought the 7990 could be awesome, and I can add another one later, right ?
I used to own a 7990, A great card. I replaced it as running a single GPU with what was available was far better for my needs, at the time I purchased a R9 290X afterwards. I have no shame in recommending either, but all in all I would choose a GTX 970.
