I have a GTX765M in my laptop
Is it worth it to setup GPU mining with this?
Not only no but HELL NO.
Laptops aren't designed to run at high load levels (like mining puts on them) and WILL overheat and often die if you try unless you take extreme measures to try to cool them that kill your profitability - and sometimes THAT isn't enough.
Running a USB miner on a laptop isn't a big deal - the software doesn't put much load on the laptop as almost all the actual WORK of mining is being run on the USB-connected device.
You should be able to run 4 x GTX 1070 comfortably on a Seasonic X-1050 - I run 3 on the X-850 with plenty of headroom - but I'd like to know where you are finding those now, NewEgg has been out for a week or so and Seasonic appears to have discontinued production on them in favor of that "Prime" series with the JUNK fan.
EVGA G2 series would be my second choice - the G3 ALSO went to a junk fan and should be avoided.
SSD on a mining rig is overkill, you don't need the extra speed - but the low-end ones are cheap enough they might be price-effective, since you don't need 500 GB on a mining rig as a general rule (BURST/STORJ/MAID is a different story).
X11 is a bad choice to try to mine with a GPU - there are 3 different companies that have made ASIC miners for that algo ALL of which are a ton more efficient than any GPU.
Scrypt (Litecoin, DOGE, etc) is a worse choice, as the ASIC for that algo are into at least their 3'd generation, each of which has gotten more efficient, and the FIRST ASIC generation was a lot more efficient than any GPU.
SHA256 (Bitcoin etc) .... even worse than Scrypt by a wide margin, don't even bother THINKING about that with anything but a recent generation ASIC AND cheap power.
