CPU: AMD A10 6800K
GPU: integrated graphics
Motherboard: MSI FM2 a55m e33
Memory: 4 GB 1600Mhz

So I'm between buying a 8GB 2400Mhz and using the integrated graphics or staying with the 4GB 1600Mhz and buyin an ATI Radeon HD 6450

I'm planning in gaming games like TF2, Garry's mod and CS Global offensive. What would you recommend?
