And i've got about 100,- euro's to spend on a new gpu. I can get a 7950 or R9 280 for that price would it be a smart buy? (I know they are exaclty the same)
I-am going AMD for sure because of DX12 (yes it is important to me (also because i've got an G3258)
I currently own a 7850 with only 1GB vram.. but that's going to my girlfriend to upgrade her 4870 512mb haha.
3gb is sufficient for 1080p for sure. I have a 280x and usually don't see more than about 2400mb usage. I think that you will be happy with the performance.
The only issue I have with 280 personally, is the lack of freesync... I would personally (again, personally) wait or look around for 285... Simply because of the freesinc. The freesinc monitors are as affordable as under 200$ so...
