pci express 2.0 and 3.0

[KellerKind]

so im gonna buy the asrock 970 extreme3 and the asus r9 270x 2gb edition but the gpu has a 3rd generation slot and the motherboard a 2nd generation slot, will they fit or not because i cant find any motherboards that has 3rd generation slot and accepts amd prossesors :/

Fatal1ty 990FX Killer has pci-e 3.0, mby some other top boards.
Ofc 3.0(it's kinda feature, like 3.0usb works with 2.0 slots) card will work with pci-e 2.0. Performance difference is really low(mby 1-2%), atm gpus r not that powerful to take full advantage of pci-e 3.0. And if u go with amd u dont need high priced board either, coz if u want faster pc u go with intel + high overclock, not amd. So dont bother overpaying, just buy 2.0 board that fits your needs(crossfire for example) and be ok with it

P.s. also, i'd better go with gtx 760 instead, dunno about pricing in your country though. the only game that benefits from r9 is company of h 2. so if u dont play this game u'd better go with gtx 760. more stable drivers, more performance, physx at least. also, gtx 760 has better oc boost per mhz.

50$ difference but u will get the advantage of smoother gameplay at 1080p. I mean u can spend 209$ and get a bit laggy card, but u can spend 259$ and get a card that can handle every game mostly.

im gonna use this gpu for playing bf4 on ultra ( 1600 x 900 monitor ) and a lot of people say that r9 270x is a great gpu , besides i am an AMD guy and i will use the copmuter for gaming and sometimes video editing :3

You can use a PCIe 2.0 mobo, no problem

BF4 prefers Nvidia cards
