If gaming (even if it's wow an older game) if the primary factor Then I definitely wouldn't recommend getting that laptop as it's not built for gaming in mind.

There is no cooling fans on it so it's going to overheat, the CPU is a duo core with low clock speed, it's probably going to overheat and have to throttle down so it's going to struggle with maintaining a steady performance.

The 8Gb of ram is good but it's a slower type of ram, with no dedicated Vram much of it will be used up o having Youtube playing in the background or chatting on Discord might slow things down.

If you want a cheap gaming laptop then I'd suggest this one

It's CPU is much faster with better benchmarking, it's a quad core so it's going to be better at running wow with other things like discord going on in the background. There is exhustant cooling fans so it's going to be much better at cooling itself then the other laptop.

It has a dedicated GPU with is going to make a massive differance, GPU benchmarking video with just the CPU on the other Laptop for comparrision it's not the fast GPU but it will run wow just fine (I use this GPU myself).
