If you want a gaming laptop with the latest gen GPU and CPU, it won't cost less than $1,000, even if they are the entry level versions. Minimum would be around $1,500 estimate.
Below $1,000, you would have to get previous gen GPU/CPU, which may not be ideal if you want 'gaming' laptop.
Check out Aftershock for customizable gaming laptops for $1,500 and above. Branded ones will cost more.
If budget is strict, then have to source for previous gen laptops from brands. ASUS/MSI/Lenovo are OK.
