You can run RW or HL on any Surface but RT (just ensure it does not run windows RT).
However, you must look at the specs to be sure you understand what you are buying.
A core I3 should be enough on the low end of the Pro 3, but the I5 is the better buy. Unless you are running just RW/HL and maybe the odd light app, it is not a lot of power. But it is cost effective, but comes with a small SSD.
But the new non Pro Surface 3 has a quad core atom, this is really a poor processor for apps like RW and HL. It sacrifices core speed for more cores, which ONLY help if your application supports a multi-threaded operation, which RW and HL do not. This is really a students dream running the latest office and such support apps. With the recent price drops its a really a steal for a full windows 10 device. I just can't tell you how well they will run. and again small SSD here. **Update** seems they have added a 128GB 4GB ram version here, but at that price point, the Pro 3 I5 128GB ssd with 4MB ram isn't much more if it is within your budget. One tip, the none Pro surface 3 is 1920x1080 vs the Pro being 2160x1440 screen.
Budget however will dictate your buying, as it does for all of us. Be mindful of the SSD size, 64GB isn't a lot, but if you run office/RW/HL that's it, it is enough. But little left to grow with. 128GB I5 with 4MB Ram is in my mind the sweet spot, and this is the one I own. The storage is great, since lets all face it, the Surface is not a gaming system. Gives you ample space for everything you need and some growth room. Windows 10 is very light, and so is all the new apps as they come, so 4MB ram will go a lot further than you think, and testing has shown, it is still the sweet spot, even in gaming.
Windows 10 is here, its lighter and in my opinion best OS since DOS 5.0 from Microsoft. So you definitely want to run it, and so far HL/RW have been near flawless with it since first preview.
Technical note - Surface is not some backwards old tech, its very forward looking. Thus is utilizes DisplayPort for video out. It has a single mini-DisplayPort, but that can be converted to DVI/VGA/HDMI as well as can be used with a MST hub to run up to three 1920x1080 screens if you disable the Surface screen itself. Do not listen to the rhetoric about this, this was the right choice, every other standard is dead and HDMI is a consumer standard.
The docking station is gold for the Surface, so good I even have one at home. But it isn't cheap.
Best accessory besides the keyboard you can buy for the Surface is the Microsoft arc mouse for the surface, its a fantastic flattening Bluetooth mouse. But not cheap.
Good luck.
P.S. The Surface is the best PC I have ever bought, bar none. Though it can't replace my main Desktop nor my Powerhouse lappy, it is just an amazing product. If I was not a gamer, and a media creationist, it would be all I need. But then I would have gotten the 256GB I5 8MB version they have now, but it is a supplementary system.
