Can this 5 yo laptop handle 5box WoW classic?

[killkat]

Turns out I need to be temporarily relocated for a couple of months from September!! I don't really want to invest 1.5-2k on a new laptop just for 2-3 months, most likely I would have little need for it afterwards. I can get use of a Lenovo IdeaPad Y510p which is 4-5 years old, would it be able to handle 5box WoW classic? Say, medium setting for master, min setting for slaves.

2.4GHz Intel Core i7-4700MQ (Haswell)
8GB of 1600MHz DDR3 RAM
1TB 5400rpm HDD + 8GB SSHD Hybrid
Dual NVIDIA GeForce GT 750M SLI Graphics
15.6" widescreen(1920 x 1080)

I got a spare 512gb ssd that I can replaced the main drive with, and probably get a 2nd 8gb ram from ebay. I assume the CPU should be ok, but how about the GPU? Since it has dual 750M SLI, would I be able to assign master to one card and the 4 slaves to the other card? Will be using ISBOXER.

Thanks alot, it'll be great if this can work.
