How does the iMac NVIDIA GeForce GTX 675MX compare to Desktop cards?

Question

I'm considering buying a new iMac and am wondering what the GTX675MX will do (have a hard time finding comparisons or tests with that). I plan to use it for gaming (part with bootcamp/Windows7 if games not available for MacOS)

I think it's a mobile card and with the space restrictions it can't have the same power as (lets say) a PC GTX 670, so next to which PC GTX cards does it fall (I have a GTX 560 in PC for example which now tends to move towards falling down the cliff on the weak side).

Answer 1

It's just theoretical, but according to the PassMark test, the 675MX should be about 30% faster than a desktop 560. This is on the PC of course and some system specific may flow into the comparison, but at least there is a good chance that performance is at least a bit bettter than your GTX-560.

See GTX 560 vs. GTX 675MX
