Lenovo y580 is also good, its pretty similiar to GE60, pretty much same components and temperatures. I got Lenovo y580, playing a bit from time to time on WvWvW. All what I can say is, its working not bad, all options on medium, till you don't meet 2 big blobs u'll be fine, when you meet one, your fps will be around 12-14, its freezing, but not that much. With culling was way better (wtb culling). On pve dragons etc, its fine.
Sorry for my poor english if there are mistakes .
wow this looks like a really good deal. pretty much the same specs as the ge60 0nd for like $300 less!
Get something with a quad core CPU, i7 with a model number ending in qm or xm and a GT650m if you can, GT640m will do as well, you won't run at max, but for zergs, you want the quad core. Check if the Sony Vaio S15 fits in your budget.
I can afford the Vaio S15, but I also came across the MSI GE60. Does GW2 even use more than 4 threads/is the added cost worth the investment?
