So what I really am asking here is if the life span of a 7950 compared to a new 8000 series card is different enough to justify the extra price I will likely pay for a 8000 series card on release.
Here are the other details of what I plan to put in my build apart from the graphics card:
Intel i5 3570k
2TB Seagate HDD
8gb G.SKILL RAM
GIGABYTE GA-Z77X-D3H LGA 1155 Intel Z77 ATX Intel Motherboard
And case obviously with a power supply...
If you wanna recommend I change something else in my current build feel free to do so, I'm open to recommendations
