I forgot to metion that thos 300$ are for the GPU and PSU both, so, help please!!

Over 600 Watt, just to be safe, and make sure it is from a reputable brand, like EVGA, Corsair, Seasonic, Antec or the like. I would recommend this http://www.newegg.com/Product/Product.aspx?Item=N82E16817152035 Its a Raidmax Semi-Modular supply, with 630 Watts of power.

Shouldnt i get a 80 plus psu? I mean i have cooler master extreme 600w but i read several reviews that says my power supply dont give more than 460 watts or something like that, idk, i would preffer 80 plus psu´s like the EVGA SuperNOVA NEX 750B1 but with that one i get 4$ more (304$) and that is out of my range, unless i find the same but cheaper...

Use a PSU calculator to check what you really need. Just Google "PSU Calculator." Here's just one of many:

Then just check Newegg or Amazon for sales to get the price you need.
Sounds like what you have is adequate.

I would not recommend using these as they vary drastically from each one to another, if you are going to to the math, to the research on your component wattages then.

80+ is good, there is no doubting that, but it is not 100% necessary, and yes, PSU's do not output the full power rating, and will degrade over years of use, but getting a higher than needed wattage PSU is always necessary, oh and one more thing, the wattage rated is usually peak watts, not standard running watts.

The 280oc is $245 at newegg and a 600w evga is $50 after rebate, both with free shipping. Or, eat one less happy meal this week and spend $304...
