I'll explain further: This is my old machine. I'm buying a big budget monster for myself, and this one goes to my 10 years-old-wanna-be-a-gamer-like-father kid. So I'm looking for minimal fuss, while the idea is good, I don't have the energy to mail DDR's.
Since there might be a cheap solution if I upgrade the cpu to 775 of a better quality, let me rephrase:
My sys is 8GB ddr2, GA-X48-DS4 mobo and Intel E8400 CPU, with a single 7850HD GPU.
1. Someone told me that the CPU bottlenecks the GPU. Is that correct ?
2. If it is, what can solve this - OCing the CPU ? to what speed?
3. I found a used Q9550 cpu - will it solve the supposed bottle-necking issue, and moreover, can it fully support 2X7850HD (crossfire) ? if not, will a q9650?
