Hi guys, This is behalf of one of my friends who is willing to go up to 2000$ for a monster gaming build.He is left the job to me and so I want to make somethings clear. First, Would it be better to buy a i7 6 core and a single powerful gpu or the best quad core in town along with a CrossfireX/SLI setup ? I know 'futureproof' is not a correct word but can the system made so to play extreme at least the upcoming 3 years ? Third,the jobs he would do would be pure High class Gaming but on a single monitor.No EyeFinity Technology required. Fourth, The most sad part , The place would be iNdia where prices are burning.I know most of here belong to the other side but still I want suggestions from all regarding the parts I should go for.
