Hello, I have an opportunity to get a Surface Pro 3 i5/128GB/4GB RAM for $770. All that I really want to do is use it as a tablet. I mean, it will be used for general use, like web browsing, watching movies (streaming and local), light gaming and using Steam's in-home streaming from my gaming rig in the office. I tried an i5/256GB/8GB for work. I thought it would be powerful enough to run the Adobe CC programs I need to run at the same time. I am a web developer/designer. Anyhow, I thought it would be great to have a on-the-go machine that I could also use for the general tablet usage that I listed above. Well, didn't work out so great. However, I really dig the Surface. So much so that I decided I want it as a tablet. So, is that a good deal and will that perform the tasks that I want it to? Is there going to be a difference between the 4GB and 8GB? Thank you in advance for your replies.
