I have three questions
1.I have one MSI r9 270x 2gb and one sapphire r9 270x 4gb
Can I crossfire these two cards?
2.what is the best PSU for this crossfire?
Cpu-fx8350
Mobo-m5a99fx pro r2
Ram-corsair vengeance 8 GB 1600 ddr3
3.does this ram support fx processors? Because I heard that it is compatible only with i3,i5,i7 and phenom processors.

1. crossfire is fine with those cards, it is controlled by AMD not the brands.
2. get a better cpu, your going to be bottlenecked.
the psu: http://extreme.outervision.com/PSUEngine do that and you can get a close estimate. I would probably go with a 850w http://www.amazon.com/EVGA-SuperNOVA-80PLUS-Certified-220-G2-0850-XR/dp/B00IKDETOC/ref=sr_1_3?ie=UTF8&qid=1432816781&sr=8-3 remember each one requires 2x 6pin connector, and remember the benefit and downsides of crossfire
3. ram supports fx processors.

You will be limited to 2gb if vram.

As tkhsda said you will limited to the lowest amount of ram on the cards and also the clock speeds of they are different it will be the lower one.

well directx12 comes out very soon so that will be irrelevant soon.
