Best configurations for photography?

[Windows Central Question]

I'm a photographer whose basic uses would be with Adobe Photoshop, Lightroom and Bridge, and often dealing with bulk images on Camera Raw. Up till now I was using Macbook pro i7, 2.9 ghz, 8GB ram. Its' only now, after 3.5 years of use, that its' started to slow down for me. As a replacement would the i7, 8GB surface laptop variant be a good enough substitute? Keep in mind that I'm dealing with far bigger RAW files than I used to 3.5 years ago!
Thanks
