I use CPUBOSS.com to compare CPUs. The move to 4K means you are looking at least the Nvidia 970 4GB RAM or better. As to the 2 pages, the usual chart means something over 32 inch 4K display. (CarltonBale chart.)
As to the games, just set them back to 1080p and let the display do the scaling otherwise you are into Titan cards.
As to the heatsink, I've never found that to be an issue.
Then again, my old setup was this.

Hey, I'm going to try and build my own rig; got about 1-2 k$ to spend, and I want either the i7-4970 Haswell or the i7-5820 Haswell E. I want to run a 27" 4k monitor ( Dell P2715Q ) but I'm not playing any fps games, so I don't need to run multiple graphics cards (sorta wondering if I need all that rezz - I hear scaling is a problem with using 4k.. maybe I get a Dell U2913WM instead??) - so I'm trying to find a good ATX mobo and graphix card that will do 3840x2160 to go with it. I am planning to use an unusual case, the CoolerMaster HAF XB: just to get a horizontal mobo - it disturbs me to see big CPU coolers (not interested in liquid cooling) hanging off the side of mobos mounted vertically, and I've always been into weirdness, so this case is the bomb for me - it was designed as a test bench...
I want to create and edit science textbook pages, and I want to be able to throw 2 full pages up side by side in Word or Publisher and still see good detail and read easily. I like to play chess, and old games (Mechwarrior or RedAlert, anyone?) on my older boxes.... But I will work it out, I'm not in any hurry. Maybe I should get a Xeon?? -Rocky
