Should I return my Sager NP9150 and upgrade my desktop????

Hi everyone! I really enjoy reading topics on this site, so thats why I decided to join!

Im a 3d modeler and I thought that my desktop has some good specs, and I should buy a laptop in case im on the go and sorts.

Lately I have been having a big question in my head.
Recently I purchased a Sager NP9150, i7-3610QM, NVIDIA GeForce GTX670m, 8gb ram, 500gb (w/ 4GB SSD Memory) Seagate XT 7200RPM NCQ Hybrid, and I paid 95 extra for a 95% NTSC color gamut screen. This purchase came up to $1,509. I just had it for a week and I already need to RMA the laptop adapter. I really enjoy the laptop, especially since I can have my games installed in this one instead of my desktop.

Laptop specs:
3rd generation i7-3610QM
nVidia GeForce GTX670m
8gb ram
500gb (w/ 4GB SSD Memory) Seagate XT 7200RPM NCQ Hybrid

My desktop specs:
asus sabertooth x58 MOBO
i7 950 Bloomfield
Firepro V5900 GPU
12gb ram
crucial m4 128gb ssd
x2 500 gb
850 power supply (not sure which one)

Since my 3d software still runs great I thought that I would just get a laptop instead. Maybe use it for school, or if im working on projects with other classmates. My thinking was why should i upgrade something that is not mobile. What if i need to take it some where? But im not sure I made the right decisions.

If I do upgrade my desktop and return my laptop should I wait till next generation of cpus to upgrade? do you think that one firepro v5900 is enough or should I do a crossfire? Do i need another gpu for gaming?

Thank you in advance for the help I greatly appreciated

Generally speaking - you don't want to use a laptop as a workstation full time - all laptops ergonomy is awful at best.

What ergonomy? With USB keyboard and mouse, where's the problem?

Yeah, with a keyboard + mouse + monitor (or at least something taller for the laptop to stand on if you want to use it's screen) + desk + chair, then it's ok. However you don't usually see ppl with laptops having even a similar setup.

Anyway, the above - that desktop is quite awesome imho, I wouldn't be looking for a replacement for a couple of years. Maybe just get a better GPU if you realy need it and you're good.

Huh, a keyboard and a mouse cost practically nothing compared to other components. I don't see why it matters that most people don't do that?

All I'm saying is that ergonomics for desktop use is a non-problem in laptops because the remedy is obvious.
