intel core i7 4970K 3.0ghz 16gb ram (2700mhz) onboard graphics 2gb 4tb hdd and 512sdd 1500w power supply

It has a 6.8 score in CPUboss. But is it slow compared to other cpus? it is 1.6GHz and up to 2.6GHz. Is it too slow for daily use of sketchup, autocad (2D only, very light use only), video editing, adobe photoshop, and web browsing? I will not use these all at once. So would this CPU satisfy...

How would these graphic cards fare for gaming at 1280x1024 resolution? R7 260x (XFX) R9 270 (Sapphire) R9 270x (Sapphire) GTX 760 (3x Windforce Gigabyte Edition)
