Comparing laptop and desktop graphics cards is a little bit like comparing apples and pears, both fruit and both tasty if you like that sort of thing but quite different. For example a GTX 960 (desktop) has an average G3D Benchmark of 5956 and a TDP of 120 Watts whereas the GTX 960m (Mobile) is 1674 and 60 respectively. The 960m consumes half the power when pushed but understandably lower overall performance.
There are dozens of GPU's currently on the market, the mobile Geforce GPU's follow the desktop processors performance sequence of, 940, 950, 960, 970 and 980 with the highest being the faster but don't assume the faster is better value for money. Bang for bucks, or speed for pounds here in the UK, the 960 is likely better value for example than the 950.
In respect of Geforce GPU's the 940m is the bottom end of the so called 'gaming' mobile GPU's and quite respectable. Compared with a desktop GPU it would be classed as mid-range as somebody wrote but for a laptop while its not the best it's a long, long way from the worst. As for running T-ANE which is a different ball game than TS2009/10 its pay your money you take your choice. Laptops are more of a balancing act than a desktop because once you have it, its somewhat difficult to change whats inside the case. Decide on your CPU and memory bearing in mind the recommended (not minimum) specification required to run T-ANE. Then decide on your screen size and finally spend to your budget on the best GPU with the most memory you can afford. If 'G-Sync' is available for the screen its nice to have as it improves the graphics further but don't sacrifice a lower spec GPU or video memory to get it. Peter
