If you have not done so, look at the tasks you wish to accomplish, and the software you will use. Some programs make extensive use of the CPU, but not GPU, or the other way around. Some will use both. That might help decide on the hardware you purchase.
My current (used ebay) laptop seemed fast until I got the K-1. It has a older i-7 quad core, 2GB video, and 32BG ram. I'm glad I purchased more machine than I needed.
Sometimes I wish there was more power for panoramics, batch or video processing, or focus stacking. On the whole I am satisfied. You might find it's nice to add a wee bit more power than you need for future need or desire.
