Start here:Can you suggest some good Specs for Gaming PC? Actually, I have no idea about it.
My budget is Round about $1500 to $2000.You need to tell us your budget, your monitor resolution if you own one, otherwise your monitor resolution you wish to buy, your expected fps and graphics settings and of course your country of origin. You can add to that if you prefer a specific retailer or a specific brand of hardware.
Just so you know, it's a VERY bad time to buy anything PC related. Prices are very high due to supply shortages, high demand, scalpers and mining.
