Does Fx 6300 Bottleneck R9-280X GPU ?
No it will not bottleneck
If you can afford fx 8320/i5 4430 then you get more fps
I am planning to go for 6300 instead of 8350 and spend rest in good cabinet , say Corsair 500R
What you say ?!
Cabinet will increase 0% performance in games.Get better cpu and settle down with Nzxt source 210 cabinet
In gaming rig cabinet should be considered at last
^^ Rightly said. While purchasing a performance rig, main concentration should be on the core components like CPU, Motherboard, Ram, PSU and Graphics card and then the peripherals should be chosen which can handle those of the core compoents you have chosen. Instead of spending huge amount on a Cabinet, get something which will get the job done and has good build quality. With the rest of the money, get a Processor like FX-8320.
Leave that i will buy both , fx 8350 and 500R XD
didn't Decided CX600M (Coz its modular and I want a clean cable management) or GS600 (Coz of LEDs and I want a good looking internal)
Yes it will bottleneck.. Go for an i5
OP can get Corsair 200R or 300R instead if he is opting for a small case offering good cable management features.
