Your RAM will work fine. As i7 said, if its CX or VS or CS, I'd avoid running the setup on it, TX/ HX is fine, so is RM (its pretty average too but will do). Glad to help :)

PSU - if its a TX or HX then it'll be fine. But not CX.

Thanks this is really helpful, so with what you recommend for x8/x8 config my RAM and PSU will work fine with this setup? a better psu you mean bit more powerful?
sorry if i ask too much this is really my first time here:)

CPU should be good enough to not bottleneck the setup, well, sadly, FX 6 isn't that good, it'll bottleneck. And almost all MoBos support CFX. It depends on what config do they support it, x8/x4 or x8/x8 (optimal). for $250, you get lot more power than FX 6 or even FX 8, while being cooler and more power efficient, and x8/x4 CFX as well:

CPU: Intel Core i5-4460 3.2GHz Quad-Core Processor (€160.33 @ Home of Hardware DE)
Motherboard: ASRock B85M Pro4 Micro ATX LGA1150 Motherboard (€60.89 @ Home of Hardware DE)
Total: €221.22

For x8/x8 config, you'd be looking at a Z MoBo.

CPU: Intel Core i5-4460 3.2GHz Quad-Core Processor (€160.33 @ Home of Hardware DE)
Motherboard: ASRock Z87 Extreme3 ATX LGA1150 Motherboard (€92.48 @ Home of Hardware DE)
Total: €252.81

Both will support CFX or 270X, but the second one will yield you slightly better results. Why to take AMD when Intel has a better upgrade path and you need to OC FX with an af cooler to match Intel's performance.

PS: Just changed the prices to Euro. And with that budget, you should go for 4690k+ASUS Z97-A and a better PSU.

Well the upgrade budget is fine(thinking around 400-500 euro dunno for sure) if i can keep my current RAM and PSU so I would mostly need CPU and MoBo just need to know if also an AMD FX like 6300 would do the trick with MoBo that's great in crossfire( I want to spend more on MoBo if that's the most important for crossfire)

What is the upgrade budget? The ones i7 suggested is the absolute best in gaming for a gamer on a decent budget.

Buy an i5 4690k, ASRock Z97 Extreme 4 and GSkill Ares 2 x 4gb 1866 1.5V cl9 ram (or your 2 x 4gb Mushkin will be OK)

CFX doesn't depend on RAM, you don't need to upgrade that. What is your current setup (CPU and MoBo and PSU)?
