Custom Resolution Utility (CRU)

Hi, noob here. I have an HP 23BW monitor (seems to be the same as the 23xi, which is confirmed at 75hz). I currently have an AMD 7850, soon to be an R9 270. What would be the easiest solution to overclock this thing the best way?

1 - I understand single link DVI and HDMI are limited, but is that still the case for a modern GPU with a good v1.4 HDMI cable?
2 - I understand that I can patch the drivers but I update my drivers a lot and would prefer not to have to patch them every time. Would I be best off going with a dual-link DVI cable?
3 - Also I have an HDMI to DVI cable and all the pins are filled so it appears to be dual link, same goes with an adapter I have laying around, any problems using one of those?

Thanks for the help in advance!!

Update 1: meh I tried both the single link DVI and HDMI cable with the patch and I was unable to achieve more than 75hz. On another note I WAS able to achieve 75hz on both HDMI and single link DVI (tested with 3 ufo tests)!!! ya can't beat dem free hz!!!

Update 2: Looks like the patch killed my video playback! I reinstalled my drivers and had a fuzzy screen at 75hz using single link dvi. Tried with HDMI @ 75hz without the patch and all is OK. Any reason why my video playback was nerf'd with the patch?
