I am going to buy a laptop for working and gaming, and I'm conflicted on whether its worth it to pay the extra money to replace the GTX 770M for the GTX 780M, thanks in advance.
I'd say go for it. I had to make the choice between a 770m and a 680m and I need to overclock the 680m for it to satisfy my needs. I'm VERY glad I spent the extra money on the 680m. It overclocks like a beast if your temperatures aren't holding you back. Same goes for the 780m.
The GTX 780M has a 50% performance increase over the GTX 770M on NVIDIA's website. It was tested with 3dMark Vantage. It's up to you if that performance increase is worth the price.
