Hey there, I just picked up a m17x r4 with 7970m. I also own a Asus G75VX with 670MX video. My plan was to see which I liked best and sell the other. Both Machines have the same 3630QM cpu. Both machines have latest drivers. I have the 670MX OC'd to +135 core and +750 memory via Afterburner. - Bandwidth is under 100. The 7970m is at stock clocks. Bandwidth is 153. I was under the impression that the 7970m is light years ahead of the 670MX, but I am just not seeing it. FPS in games is 1-2 frames better in almost all cases. I have heard that there are problems with Enduro, but not sure if this is what I am running into. Also, small issue...GPUZ will not load on the Dell for some reason. Any ideas?
