10000rpm drives are a hoax. they are no faster than a 7200rpm drive. Not worth the money at all.
You don't need more than 8gb RAM for any gaming at all.
If you are planing to game, get the fx6300 and an $80 mobo.
Use the extra money to get a 7870.
Gaming is 90% GPU and 10% CPU
I'm also a web developer/Graphic Designer so i kinda need the ram for photoshop and stuff. But i see your point on the CPU and the 80 mobo.
What would be The difference in performance if i change the ASUS for this one ASRock FM2A85X Extreme6 FM2 AMD A85X (Hudson D4) HDMI SATA 6Gb/s USB 3.0 ATX AMD Motherboard and change the 8 core for the 6 core you recommended
I'm very concerned as well for the motherboard durability thats why i choose this one.
