yeh.
I was looking at Asus G752VY with 8VRAM, but some people keep saying it is overkill ...
Overkill? Lolwat?!
If that cost $3000 it's severly overpriced. The biggest issue being that the 980M compared to the GTX980 is a crippled piece of shit.
For 3K you can get a faster CPU (Asus GT73 with the newer 6820HK for example), faster GPU (GTX 1080 fall well within that price), 32gb ram/ 512gb SSD (+ a HDD in the 1-2TB range) with a 120hz+ G-Sync screen.
If you want to save $500 or so you can go eqvivalent machine with a GX1070 (back in the 3K range again you can get GTX1070 SLI).
Personally I also wouldnt bother with the machines that pack an extra HDD. 512gb SSD is enough, hell even 256gb will be enough if you dont have a ton of games/applications. Most data should be on external network drives anyway.
Or of course you could go a 1.5K GTX1060 laptop just fine, lol. SHould be same CPU/ram/ssd etc, maybe a little cheaper screen.
The extra 1.5K you save I recommend spending on beer and hookers. Not necessarily in that order.
