So i want to buy a gaming desktop but cant decide between an ASUS ROG8580 or a custom built one.I know most of you will probably say build one yourself but im not good at technical things and i live in Turkey so there arent many custom builders.Also i find this ASUS most reliable because it comes tested from a big company where on the other hand a custom built one could have some problems.Please help me choose and also if you can build me a PC from this site it would be awesome http://www.teknobiyotik.com/pc-sihirbazi/akilli-pc-sihirbazi.html (the site is in turkish but i hope you can figure out which category is what! )
