R8 and R9 are the newest ones
CPU? you can go with the APU of AMD di mo naman kelangan ng 6 or 8 cores when it comes to gaming unless you wanted to do OC
plus APU saves you more money
Mobo? MSI are good ones too , if you have a little cash to burn i'll choose ASUS or ASROCK for generic , and if you want an upgrade on your RAMS make sure kung hanggang saan yung RAM nung mobo mo kung kaya ba neto sa mag OC sa 2300
HDD yeah 500GB are good but it depends if you wanted you can go for 1TB or in the future add an SSD if you want your PC to boot faster
SSD are commonly use for OS and other needed programs , plus it's it expensive as hell
RAM? I'll go for G.Skill ,1600 is good for gaming
PSU? like we said here , wag mag tipid sa PSU , its the back bone of your computer if it fails then your parts will fail , go with the trusted brand with Bronze , Silver or Gold on them
Case? Personally I don't give a crap if it's a glow in the dark or it has a big side window as long as i have Wind Circulation , Clean cable Management and more space for my HDDs to add on and some GPU are longer , my Current Case is a Corsair 200r i can do many things on it on the future such as radiator on the top or dual fans
GPU? i think the one you are looking for is now called R8 Series in AMD , not sure if it is , since im running on Intel Nvidia is the best choice for it
the new GPU's and APU's are less power so you might add the power wattage you need before you burn some money on a 600W PSU
beQuiet's PSU Calculator is the one i use
and if your looking for a place to buy your parts : look for a computer shop trusted by the Computer Community in TipidPC
