FX series motherboards

I'm in a battle between AMD FX-8350 and AMD FX-8320 (I'll probably end up with 8320)

Also I would have to choose between 4 motherboards:

M5A97 R2.0 LE (Costs: 580HRK cca. 110$)

M5A97 R2.0 (Costs: 620HRK cca. 120$)

M5A97 R2.0 EVO (Costs: 800HRK cca. 160$)

M5A99X R2.0 EVO (Costs: 980HRK cca. 200$)

M5A99FX R2.0 PRO (Costs: 1000HRK cca. 205$)

I'm on a tight budget so I would like to go for the cheapest one. Also, I'm not into overclocking (AMD chips with my cooling would burn on stock speeds, overclocking is definitely not for me) The rest of the rig (Ignore the cpu and motherboard, that is something you decide)

Note: I'm really worried because the GPU is PCI-E 3.0 and I think that all of these motherboards have only PCI-E 2.0 ports

Do not worry about pci-e 3.0. You can throw a 290x crossfire set up on that M5A97 R2.0 LE and never bottleneck as far as the band width goes. Pci-e 2.0 is perfectly fine for current graphics cards and Pci-e 3.0 is really more for future cards. All the asus boards listed are great. Pick one that has the features you need and then take the extra cash and put it into your graphics card if you haven't already bought it.

Also you should probably just get the 8320. It's so close to the 8350 in terms of performance and i think its a better choice if your on a budget.

Thanks, but which graphics card should I spend my money on? Should I stick with the Radeons or should I get something from nVidia (offtopic)

Well I'd go for a Gtx 760 http://pcpartpicker.com/part/msi-video-card-n760tf2gd5oc it will be stronger than the 270x. And if you could afford it a Gtx 770 would be a huge improvement although the 760 already is over the 270x. Here's a good one http://pcpartpicker.com/part/gigabyte-video-card-gvn770oc2gd I'd tell you to get a 280x but the price on them is up into the $450 range with how good they are at litecoin mining
