Your config sounds good Ulco, though I'd go for 8GB DIMMs for maximum future upgradeability. Get 32GB *now* if you can, or 16GB in 2x8GB config. IF the motherboard is quad channel for memory then do either go for 4x8GB (32GB total) or 4x4GB to take advantage. Quad channel memory is not something that an application needs to do anything whatsoever to take advantage of, it simply provides more memory bandwidth to the system as a whole. Sure you could say that some applications *benefit* more from multi-channel memory (i.e. applications that are more memory-bandwidth limited), but it's not something the app is necessarily doing to take advantage of it. Memory-bound applications should inherently benefit on such systems.
As for the graphics card, it will be acceptable for TG use and it's quite cheap. You can always upgrade later if you want more, so I'm in favor of the basic solution, especially if you can spend the extra money (rather than the 2x expensive card) on more RAM.
Laptops are not usually designed for long periods of constant 100% CPU use, so there *can* be heat issues. This can generally be mitigated with proper surface placement and potentially active cooling (laptop cooling stand with fans) if needed. Most laptops will do OK for occasional rendering if you ensure it's placed on a flat, hard surface (e.g. desk) and that air entry/exit paths are clear of obstructions.
